The now long gone owner of the Aub Zam Zam on Haight St was a beloved notoriously cranking bastard. Friends of mine go to a hole in the wall Sushi place that is also run by a notoriously cranky guy. Show up with four people and he'll kick you out.
Bruno’s reputation was making the best martini’s in San Francisco. If you minded your P and Q’s you would get served and not face any abuse. But if there was any hint of jerk in you, Bruno would 86 you the hell out of Aub Zam Zam.
It's old school San Francisco.
