I've been to the frog twice...both times I had knowledgable staff that knew a lot about beer....that gives it a thumbs up for me. Like other reviews they were out of many of the beers they listed in the book, but had other great beers that weren't in the book. Perhaps an updated list by week would be the answer...
If you are a beer geek, this place isn't far off the strip and has the best selection of beers in the city. Well done.
