Hubby and I will be winding up our vacation with 4 days in San Francisco. We are sophisticated NYers and do not mind spending money if it is worth it. We do not eat sushi or spicy food. That said, we are torn between Fleur de Lys, Gary Danko (second time), Ritz Carlton Dining Room, Acquerello and Delfina. We also need some casual lunch suggestions. Is Kokkari good? Would any of the above work before an 8 pm performance of Beach Blanket Babylon or can you recommend somewhere good in North Beach that takes reservations? Thanks in advance.
