Shanghai's cuisine, like its people and culture, is primarily a fusion of the forms of the surrounding Jiangnan region, with influences sprinkled in more recently from the farther reaches of China and elsewhere. Characterized by some as sweet and oily, the method of preparation used in Shanghai, it emphasizes freshness and balance, with particular attention to the richness that sweet and sour characteristics can often bring to dishes that are otherwise generally savoury.

Shanghai local cuisine, or Shanghainese food is also known as Shanghainese cuisine, and authentic Shanghai cuisine, mainly features freshness, especially the fresh fish and shrimps, bright colours, and original flavours. Boiled eel(锅烧河鳗), three yellow chicken(三黄鸡), fried shrimp (油爆河虾), Shanghai drunk crab(上海醉蟹) etc. are the typical local cuisine.
