Word on the street is the test of a true Irish pub is the beer on tap. O'Brien's, the self-declared hoppiest place on earth, impresses San Diego beer fans with an extensive and unique selection of local and international brewers. Try select drafts from Alaskan Brewing Company, Alpine Beer Company, Ballast Point, Bear Republic, Boddingtons, Brouwerij Affligem, Brouwerij Het Anker, Green Flash, Hollister, Lost Coast, Marin Brewing Company, Port Brewing, Russian River, and Sierra Nevada. The only thing to out-do O'Brien's beer lineup is the signature spicy beer cheese burger.
