Bengbu (蚌埠; Bèngbù) is a small city North of Hefei.
Taxis start at ¥5.
A local specialty is river crayfish cooked with lots of spices. There is a whole block near the center of town that consists mainly of restaurants serving this and other dishes.
Turn right at the end of that block, there is a nice small trendy restaurant on the right. Specialties are ice cream and Japanese/Taiwan style light meals. The jiaozi are excellent.
