I'm looking for a casual but nice place for lunch to celebrate my birthday with two girl friends. I want a "ladies who lunch" sort of place, where we can dress up a little bit. I was thinking of places like the Neiman Marcus Rotunda or the Cliff House, but those are both a little on the $$$ side, and I'm looking for something that's $$. I thought of Cafe Claude, but not super into the idea, as well as the Nordstrom Cafe, but not super into that idea either...though both those are more in the price range I'm looking for. Since I'll be doing this over the weekend, I'm open to brunch options as well, but prefer lunch. San Francisco or East Bay is fine.
