I found my self drinking here every late night when I was at the Red Rock for a conference. Comfortable seating, attentive well dressed staff, and the drinks were always good.
If you like people watching, this is the place for you... I was highly entertained every night! They play some pretty chill music like a club... maybe that's why they were offering "bottle service"? Our waitress Barbie was awesome and she always made sure I was doing good and would join in our conversations at the table sometimes, which was enjoyable.
