I went to Bacchus with my partner and we both agreed that we had one of the best meals we've had in London for a while.
The food was superb: so many new unique combinations of flavours and well presented dishes. We went for the full 9 courses with the wine pairing and I would recommend that you do this if you are going to go here.
The service was great: our waitress was really friendly and just attentive enough and when we asked about the inspirations for the dishes, the chef came over to our table and had a chat with us.
I would recommend Bacchus to anyone who is looking for something special.
I also loved that there was music on the background (and I'm not talking about elevator music.they played the smiths, kings of leon, amy winehouse, the kooks...) which made the atmosphere a lot more relaxed than in many other fine dining restaurants.
By the way, the picture you have of Bacchus must be really old as it now looks nothing like that now! :)
