I booked a table for lunch for my wife's birthday. Head waiter remembered I mentioned (in passing when I booked) it was a birthday meal, and welcomed us warmly and with complementary glass of champagne. The service continued to the same standard, and was faultless throughout – friendly and attentive, but not over-burdensome. The food was excellent, with flavours (such as a fantastic Amuse-bouche) and presentation comparable to a recent lunch at Maze. If I were being really picky, perhaps slightly too much salt in pheasant main, but the jus more than made up for this, and was truly scrummy. Meal was accompanied by half a bottle of a well priced and nicely balanced Sancerre. Overall, compared with a good number of Michelin starred restaurants I've eaten at in London recently, this was certainly of a comparable standard, but when you look at the price of the lunch menu (£10 two courses, £15 three courses), you cannot help but be struck by the amazing value for money for food of this quality. We will be heading back to Tristan for dinner soon, and hope to be similarly impressed!
