If you're in Vegas and wanting to check out a great new restaurant at a new casino, Rose. Rabbit. Lie. is a solid choice.
I suggest starting out with a specialty cocktail in their speakeasy-esque side bar before your dinner. Then enjoy the dining room with interesting cultural art, live music, and wonderful ambience.
Order a bunch of plates for your group, especially trying the rabbit, salads, and foie gras.
Caveat: we had a group of about 9 and were seated at a tall table. The host was adament about squeezing 5 on one side (making things less comfortable for us), rather than have one person sit on the end. I understand the claim of "my servers need to get through this aisle," but I also believe a trained server worth their dollar could have navigated past just fine.
