Located in a historic Lafayette building, Petars is a funky place decorated with a Knights-of-the-Round-Table-type English theme that seems to attract the white-hairs. The main draw here is Diamond Dave Hosley, who has been performing every Wednesday through Saturday since 1986. Equipped with his Roland keyboard and headset mic, Hosley sings everything from oldies to current hip-hop hits in Petars bar. In addition, Tuesday nights feature Irish songs from Snead Healy, and Sundays feature blues with the Rhythm Doctors.
You can find better beer elsewhere, but this Berkeley outpost of the small national brewpub chain wins points for its family-friendly vibe, super-spacious industrial-chic interior, and massive burgers.
