Yuxin is by far the best Sichuan restaurant in Shanghai. It's also the biggest, spread over the whole third floor of an office building. There are 26 private rooms and seating for twelve million, and they manage to get authentic, complex, spicy Sichuan cuisine right for just about all of them. The chuanbei liangfen -- a misleading rice "jelly" on the menu -- and the tea-smoked duck are among the standouts.
