Can someone recommend some nice restaurants for lunch in downtown SF or near Civic Center that feature comfortable booths? I'm having lunch in a few weeks with a wonderful elderly man who has a hard time getting around, but who still loves great food. We were going to have lunch at Zuni until I realized that he would be uncomfortable sitting in their chairs. He used to love having lunch in those big plush booths at Stars, and prefers a booth to a plush chair. As he walks with a cane, he also needs a place with no steps to navigate. What are our options for California cuisine/French/Italian? Soluna, across the street from the Asian Art Museum has great booths, but I'd rather go somewhere a little more upscale. Any suggestions?
