I'm spending the weekend with a friend in SF and am in need of recommendations for a pre-theater (curtain at 8 pm) dinner near the War Memorial Opera House for this Saturday night. Friday night we're eating at the Dining Room at the Ritz Carlton (where we are also staying). It's a special weekend (and thus the splurge on the Ritz). So, I'd like something nice, though it doesn't need to be fancy. Good food and atmosphere are more important.
