The food scene in SF is very elaborate. It has its ups and downs. The best of it: Mexican, Chinese, Korean, Vietnamese, Japanese, Thai, Burmese and Indian. Also a good amount of fine dining, American and modern cuisine. The lows are salads (better make it yourself), over-priced Californian cuisine (like an $8 peach at Zuni Cafe), Mediterranean (still looking for decent shawarma in the whole bay area) and desserts (too sweet and rarely worth the price).
