After walking for a few hours around Vegas, even though we were about 80% inside, we were ready for frozen alcohol. The back bar has maybe 15 barstools and we were lucky to grab 4 together about 2:00 on a Saturday. It was busy and loud, but the bartenders were fast with the drinks...and refilling our water.
They did give some other people a hard time, a middle aged woman wanted to order some drinks for her bachelorette party while they waited for a table and the bartender made her bring back all of the people in her group including her 75 year old grandma. He carded all of the 25-30ish year old women, including the one who was pregnant and just wanted water. It was awkward.
