I will be in Berkeley Sunday night to take my niece to dinner. The problem: I need to find a restaurant with good plain cheese pizza (she hates Zachary's deep dish), or a good plain hamburger, or some other sort of plain diner food. I would rather go to Chez Panisse or some local Indian place, but we must cater to her needs (she's a freshman at Cal). Any suggestions? I'm at my wits' end here. Thanks in advance.
