I went to the one in Honolulu, HI, and it was ok.
PROS:
1. unlimited tasting
2. good variety.
CONS:
1. nothing is on tap, all bottles.
2. It's just event staff pouring beers, they know nothing about the beers, so don't expect to talk about the beers.
3. if you don't get in early, the lines are long to taste the beers.
