My wife and I came here on a Wed night and the restaurant was not busy at all, so I can't really comment on what the place would be like on a busy night. What I can say is the following:
Food = amazing. Our friends gave us the tip to order the mushroom and truffle ravioli... which is not on the menu, you just need to know to ask for it... strange I know - it was incredible!!! I also tried the sweetbreads which was also amazing (on a side note I tricked my wife into trying sweetbreads as she did not know what they were - she loved them until I told her what they were. We had a similar experience with foie gras, and a few dim sum dishes - never gets old to me)
Service = awesome - an Italian gentleman walked us through the menu, made some nice recommendations for wine, and let my wife taste a selection before ordering a glass, also got us a serving of the "not on the menu" mushroom truffle ravioli
Overall, we really enjoyed our experience here and will likely be back soon.
