As far as Las Vegas brewpubs go Gordon Biersch is OK. Prepare yourself for a TGIFridays type of atmosphere, decor, and food and you can do fine. The beer, though, is decent, but unspectacular. All are fair representations of a narrow range of beer styles, mostly lagers. Not a lot of variety in the flavors, but reasonably well made beers.
The service was OK, but not great, when we visited.
