Guyi is an institution of a Hunan restaurant in Shanghai, among both foreigners and locals, for its upscale environment and excellent fiery food, unaffected by local tastes. It's a step up from almost all other Hunan restaurants in Shanghai, and though quality has wavered in the past, is still a solid bet. Cumin-crusted ribs (ziran paigu) are their signature. No reservations after 6.30pm, so expect to wait.
