What a great find!!! I had stayed at the Chesterfield Mayfair Hotel on numerous occasions for work, and never thought about eating in the hotel restaurant. And why would you, when you've got great restaurants surrounding the hotel. But I thought I would give it a try, and I was blown away! Takes a lot to impress me, having experienced and dined throughout my travels. The service is impeccable. The attention to the tiniest detail is faltless. From the selection of salts from far off places, to homemade petit fours served with the coffee. I had their goats cheese terrine to start, followed by the pork belly. You would think that pork belly would be quite a heavy ingredient, but the way it was served and the pickled Fennel, and microherbs, made it light, full of flavour, and beautiful. I was there for work, so my colleague and i had had lots to catch up on, and the fact that the restaurant is tucked away, meant it wasn't overcrowded and loud. You can hear yourself talk. The waiters are discreet, so much so, you don't even notice them topping up your glass. My point is, you can have a great lunch, and have a conversation and not feel as though you're being rushed off, because they need the table. Definately a place I would recommend, the whole environment feels like an exclusive mayfair private club, but its charm is warm and inviting. I don't know where they picked their staff, but well done, because they seem to always remember their regular customers (i'm a convert now.) and the welcome at the door is always genuine.
