The place is very cozy and attractive. I went on a night when it was snowing out and still the place was full. I agree that the booking system still has its kinks and I wasn't quite sure I had a reservation or not until I showed up and luckily I did, though I suspect it was a result of the bad weather.
The food we had was overall good, but the portions are small. This appeals to me because I like to try a few dishes. If you have a big appetite be sure to order lots of food at the beginning. It took awhile for us to get more food when we decided we wanted to try other things. The escargot was not very good, extremely garlic-y and swimming in a soupy sauce. I could barely find them.
The service is Parisian style, and I mean that in the way that they are not service oriented. Be prepared to ask for everything, rather than being asked if you need anything, including more drinks. The bouncer was rude and slammed the door into my friend on the way out and then yelled at her that she should realize he was standing behind the door between the two exit doors.
The lounges were closed when we were there, but we had a peek and they looked really cool and nice. Overall i think this could be a really cool place, just set your expectations accordingly. It's not high end and you don't get treated that way.
