After a lot of research, we (brother, cousin, me) chose this as our fine dining restaurant of the trip. The ambience is fantastic - dark, comfy seating, great decor.
Service was excellent. When I didn't like the drink I ordered, the server let me taste something else before pouring. Every course was explained and questions asked to the chef and answered (my brother is in culinary school and had a few questions). The timing was perfect - not too fast or slow.
The food was amazing. My brother and cousin ordered the 4 course tasting menu and I had the 6 course chef's menu. We shared each course which was perfectly prepared, presented and sized.
They have an absinthe cart that we did not sample, but it looked interesting.
I would not hesitate to recommend this restaurant or eat there again the next time I'm in Las Vegas!
