Zédel is my absolute favorite restaurant in London. Beside the fact that I love french cuisine, Zédel is aesthetically pleasing, very reasonably priced, is good for any occasion, and of course - delicious. My favorite is the bouillabaisse and a bottle of the Bordeaux Superior.
I grew up in the countryside, and if you're ever in need some instant escape from the city, this place is like a time warp. It's a huge space full of over grown mausoleums and graves, feels like a movie set. They also do tours.
