I'm trying to find a sushi joint in or near Berkeley that could accommodate perhaps 15 people for my girlfriend's Berkeley. My personal favorites (Temari, Genki and Bonsai) don't seem very conducive to this. Something on the cheap end that isn't sketchy that's cool with a big group of college students would fit the bill. The first thing that comes to mind is Party Sushi, which I have not tried but understand is quite cheap. Any thoughts?
