Absolutely fantastic both times I've been here.
First time was on NYE a couple years ago, just to stop in for some drinks and check out the atmosphere. We had absinthe cocktails that were to die for.
We then returned for my birthday dinner last year and had incredible food, too. I was pregnant at the time & bummed I couldn't partake of any of the really cool cocktails they have, and they were so awesome that they made me some fancy, non-alcoholic "cocktails" on the fly -- the server just asked me what kind of flavors I liked, and the bartender came up with some kinda awesome thing with cloves stuffed into an orange slice that was easily one of the best drinks I've ever had, alcoholic or not.
The atmosphere is funky and very interesting, albeit a little claustrophobic with the tables very close together and so much going on all around you. I like that sort of thing (it reads more "cozy" to me), but if that's not your cup of tea, be warned.
