I just visited there. Beers are nice, the brewery itself is really nice. The casino, on the other hand, wasn't so kind to me
We had a nice bartender who gave us all beers on tap for our sampler so we could try them all. Score!
Edit: If you're ever there M-Th, check out Todd English's P.U.B. (at the Aria) for a great selection on happy hour (1/2 off brews). They also have a 7 second challenge, where any beer ($10 or less) that is drank within 7 seconds is free.
