SquareMeal Review of 34 Mayfair

Gold Award

Part of Caprice Holdings (which also includes Balthazar, Daphne’s and J Sheekey among its glittering portfolio), 34 Mayfair is a restaurant that makes no apologies for its over-the-top nature. Serving up the sort of old-school hospitality that’s becoming increasingly hard to find as London restaurants go more casual, diners at 34 are greeted by a top-hatted doorman, before coats and the like are whisked away by the hosts on the front desk.

Once you get to your table, you can drink in the art-deco-style interiors that look timeless but date back no further than when 34 opened in 2011 – think table lamps, tan brown leather banquettes, a partially open kitchen and a sleek marble bar. Decadence is the order of the day when it comes to the menu, too, which has steak at its heart but also does a good line in seafood dishes such as miso-glazed fillet of halibut or chargrilled octopus.

We kicked off with a punchy shrimp cocktail, a retro starter that we’re happy to see being revived on London menus. Plump shrimp still in their shells hang off the edge of a bowl featuring a classic Marie Rose sauce, while finger bowls are provided to help you clean up.

From the mains, the USDA Prime ribeye is a beast of a thing that’s cooked to order and boasts a marble texture and just the right amount of fattiness, while the lobster mac ‘n’ cheese is as fabulous as it sounds, finished off with a shower of black truffle shavings – as one reader says, “to die for”.

The extravagance continues on a dessert menu featuring ice-cream sundaes and delightfully messy sugar-dusted doughnuts. Indulgence might be the order of the day at 34 (weekend brunch is the stuff of Mayfair legend) but you can eat healthily too – lighter choices include salt-baked beetroots and spiced stone bass, while there is also a dedicated vegetarian menu.

Close-set tables can make the dining room feel cramped when service is in full swing, though staff who are ever-attentive to diners’ comfort make sure the whole experience feels very slick. High prices are inevitable considering where you are, but great service and some truly delicious food mean there’s no shortage of punters happy to cough up. As one reader coos, 34 is “fabulous in all respects”.

About

34 Mayfair is an up-market, glamorous restaurant in the heart of London's most fabulous postcode, as nodded to by its name. The central space is a smart dining room with polished wood flooring, red leather brasserie seating and a grand art deco bar. 

The outdoor terrace which sits along the front entrance is a pretty place for food and drinks in the summer, while indoors, large windows flood the space with light in the day and atmospheric lighting making the dining room a buzzy place to meet friends, colleagues or a date for lunch or dinner. 

On the menus, you'll find a breadth of modern European dishes, but the rotisserie and grill are certainly a talking point. The a la carte menu starts with small plates like seared scallops with soy glazed pork belly, dashi and shiso butter, alongside Robata grilled octopus with smoked black bean, aji amarillo and avocado, as well as Dorset crab tart with kohlrabi, green apple and yuzu jelly.

The main menu spans salads and fish dishes, plus signature meat mains off the rotisserie and grill. If you fancy something a little lighter, the 34 Caesar salad combines a smoked garlic and parmesan dressing with Ortiz anchovies and the option to add rotisserie chicken. There is also a raw bar, with dishes like salmon sashimi, steak tartare, and shrimp and seabass ceviche. Pescatarians will enjoy the likes of Indonesian BBQ sea bream, alongside Dover sole and the fish of the day, but if steak is on your mind, check out the Wagyu selection, sirloin, fillet, rib-eye, and cuts for two.

When it comes to drinks, wine connoisseurs will want to see the 'legends of wine' list with rare and vintage glasses from the cellar, while the cocktail selection has some creative twists such as an Old Fashioned inspired by banoffie pie.

AVOID AT ALL COSTS. The most arrogant people in the hospitality industry

If you want to deal with some of the most arrogant, dismissive and unprofessional people I have ever encountered in the hospitality and events industry, then by all means book your special event at 34 Mayfair.


Our wedding reception dinner was cancelled just two weeks before our wedding. Rather than showing empathy, accountability or a genuine desire to help find a solution, the Commercial Director of the business showed indifference and arrogance that was frankly astonishing given the significance of the event they had agreed to host. Here is what happened exactly:


We initially chose 34 Mayfair for our wedding reception because of its reputation and the quality associated with the Caprice brand.


Our initial enquiry was for 23 May 2026, however this was subsequently changed and confirmed by the venue for 16 May 2026 via email. Following this confirmation, we attended a venue viewing, paid our deposit, signed the booking agreement, engaged suppliers, discussed entertainment, and continued planning our wedding on the understanding that the booking was secured.


Several months later, we were unexpectedly contacted at 6 pm on a Friday and asked to confirm whether our event was actually taking place on 23 May. This came as a shock, as the venue had previously confirmed 16 May and had continued planning discussions with us on that basis. Had the date not been available, the consequences for our wedding would have been significant. To them, this was so simple, and our event manager didn’t even reply to our email or gave us a call that day. Such a coward way of handling things.


While the venue later acknowledged there had been an internal error, we found the handling of the situation extremely disappointing. Rather than taking ownership and working collaboratively towards a solution, the communication felt defensive and dismissive. At no point did we feel reassured that the seriousness of the mistake was fully understood.


As discussions progressed, further inconsistencies arose regarding guest numbers, fees and other aspects of the booking. One of their colleagues promises and assured us different things while showing us the room and these were later denied. We were also asked to agree to terms that did not appear in the signed agreement. And this was “pay us 15% upront” When we questioned these points and sought clarification, the response from senior management was ultimately to cancel our wedding reception booking altogether. This is literally a contract dispute and dictatorship, showing no remorse towards the meaning of the event specifically.


The most disappointing aspect was not the mistake itself, but how it was handled. Mistakes can happen in any business. What matters is how they are addressed. For a wedding, clients place an enormous amount of trust in a venue. We expected accountability, empathy and a genuine effort to resolve the situation. Instead, we were left having to secure an alternative venue at short notice after months of planning.


We have incurred additional costs and significant disruption as a result. Whilst a refund was offered, this does not change the fact that a confirmed wedding booking was cancelled by the venue following a series of internal errors and miscommunications.


Based on our experience, we cannot recommend 34 Mayfair or Caprice Holdings for events. I will never forget the ARROGANCE of the commercial director, and the customer care we received here, especially from such a famous hospitality group. You suck 34!

Do not trust 34 Mayfair with a wedding or private event

We booked 34 Mayfair for our wedding reception in May 2026. Two weeks before the date, we were forced to move venue because professional trust had completely broken down.

Throughout the planning process, we experienced persistent coordination issues: staff turnover, poor continuity, contradictory information, and ongoing confusion around basic contract points including guest capacity, drink inclusions, fees, and logistics.

The critical breakdown occurred when senior management became involved. Instead of resolving these operational issues, the Commercial Director informed us that the venue did not feel comfortable proceeding and wanted to unilaterally cancel and refund our booking 14 days before the wedding.

When we made clear that we did not accept a unilateral cancellation of a signed agreement, 34 Mayfair offered to proceed only under a series of new, last-minute conditions — including the mandatory upfront payment of a discretionary service charge.

We expressly pointed out that an upfront service charge payment was not required under the signed contract, which provided for settlement at the end of the event. Despite this, senior management stated explicitly in writing that if the service charge was prepaid, the service would be “assured at 150%”, but that without this non-contractual prepayment, the same level of service “could not be guaranteed under the same conditions”.

To condition the basic quality of a wedding reception’s service on yielding to a last-minute, non-contractual financial demand is an extraordinary violation of professional ethics. We could not enter our wedding day wondering whether our guests’ experience would be compromised if we did not accept these altered terms.

Our deposit was refunded, and our replacement venue stepped in at the last minute and delivered beautifully. However, the late-stage disruption, uncertainty, and stress caused by management’s actions were significant.

We are reporting this matter to Trading Standards regarding unfair commercial practices and are preparing to pursue formal legal action in court for breach of contract and consequential losses.

I strongly advise couples and private event planners to avoid 34 Mayfair for any high-stakes event where reliability and contract integrity are essential.

Bad service! Not worth the hype

We didn’t have a great experience when dining at 34 Mayfair yesterday! Some of the waiters had an attitude especially the women at the front door, and the lady who walked us to the table. We had to wait for 20mins before we were given the table, and we had to stand in a small space right near the front door! They didnt even offer us some space near the bar area, we had waiters barging into us whilst we were waiting as it was so busy and not great experience! When we book a table I would expect to not have to wait for more than 5 minutes. The main course was served really late we had to wait nearly an hour for it to come out, and then they had the audacity to ask us to leave the table for another booking, just as we were about to order dessert! I would expect more from this restaurant, very poor service, stuck up waiters too! and we will never dine here again!

Nice experience but less vegetarian options!

Food was delicious and perfectly cooked however there were not enough vegetarian options. Service was quick and efficient. We enjoyed our visit and it could have been better if there were more vegetarian choices!

Smart, sophisticated, calm and frown up dining. Understated and off the 'Essex Crowd' radar!

Wonderful evening
What an incredible experience, starting with a choice of tables, despite the restaurant being busy. We wanted a romantic evening and didn't think sitting next to a loud table of 8 people would be the answer, so were given the choice of 3 different tables, without a hint of this being inconvenient. The service was slick and the sommelier was extremely helpful, with a great recommendation. I've dined at 34 previously and had forgotten quite how succulent the steak is. Always a good sign of a well rounded menu when you can't choose between 3 different starters, but the decision to go with the shrimp cocktail was a wise one. So refreshing not to be asked to settle the bill because they "need the table back" which seems to be par for the course in most high end restaurants these days. Can't wait to return.

A comically poor showing
When things go wrong, a really good restaurant takes this as an opportunity for showing their clients that they really care about them and make sure they fix it and that everything from then on goes even more smoothly than usual. At 34 we recently had what can only be described as a toxic mix of poor service, dubious food and strange reactions, which, if on TV in something such as the classic Fawlty Towers, could actually be funny. However in Mayfair, at this price and at this aimed-for level, it was simply shocking. Service receives it second star only because two of the eight or so waiters we saw during the evening saw the problem more clearly than the completely disorganised front-of-house staff. The only positive point is the the nice US sourced beef, but it does not make up for a completely random Italo-American botch of a menu and a dining experience which can only be described as mechanical: every course is served by a different member of the team. Every wish is ‘processed’ by the waiter one has just spoken darting off to go and check with the head-waiter and it seems reporting lines are very long and complex. This is strange to say the least, as 34 bills itself as a easy-going ‘good time’ restaurant which aims to convey a slightly festive atmosphere. Therefore slight shortcomings on the culinary side could be accepted as a trade-off for things generally being fun and entertaining. However, the atmosphere is not all it is made out to be and the food is frankly hovering somewhere between awful, perplexing, poorly thought out and sorry to say ‘wrongly prepared’. The foie gras could be used to explain why it has been forbidden in California. Very sad as on the face of it, the restaurant 34 sets out to be is exactly what this part of London would have needed. The famous group behind 34 could sure do better.
