Hi, I plan on abducting my husband in late August for a surprise weeknd trip to San Francisco to celebrate his birthday. We'll have time for two lunches and two dinners. Given the short amount of time and the abundance of choices, what do you local chowhounds say are the absolute must haves? All cuisines and prices are okay. We're looking for a unique California experience. He has never had Dungeness crab so we should work that in somewhere. On a related note, any hotel recommendations? We'd like something fun and romantic but relatively close to retaurants and (hopefully) the Asian Art Museum. Thanks in advance!
