Costa Mesa Goat Hill Tavern 1380 Newport Blvd. That's a lotta parts, but it's a big place. Most often between 90 and 110 different beers available as well as a massive selection of spirits. No longer a mega-tap. Cut back from 105 to 30 because the beer wasn't moving quickly enough.
Food ranges from Middle Eastern to pub grub.
You can literally stroll across the boardwalk and fall into the marina. Sacramento River's End Brewpub 3535 Fair Oaks Blvd. Not a brewpub, but more than 50 taps. 61 taps in an intimate bar. Rare taphouse in an area, just south of Coors Field, swarming with brewpubs.
