I would 2nd seeing Carrot top. There were things in his show that you will not forget!!
I would recommend a place to eat that is like an old speak easy. Capos Restaurant is a great place to eat. Even finding your way in is fun. The night I was there they had a guy playing the piano and the food is outstanding. A local recommended it as his favorite Italian restaurant. 5675 W Sahara ave. They make their own meatballs and people would just have them for their dinner.
I would also recommend a trip to the Red Rock area. Beautiful. I didnt get to the Dam but would enjoy that also.
