The only reason I agreed to walk into this place was because I was seconds away from drinking myself to death. I ended up really enjoying it though.
You need to know a few things before you go. It's overpriced (what isn't in Vegas). It's small. It can get a little boring. It's possible it just feels boring compared to everything else though.
All complaints aside I thought it was a wonderful way to get out of the casino for a while and put the bottle down. If you need a PG activity I say go for it!
