Visitors to Tianjin can see fried dough twists, a traditional Tianjin snack, sold almost everywhere in the city. The most famous ones are the "18th Street Fried Dough Twists", so called because they are made at the former 18th Street.

The Guifaxiang Fried Dough Twist General Shop is now situated at 568 Dagu Road South in Hexi District, the original location of the former 18th Street shop. It produces the traditional 18th Street Fried Dough Twists. The dough twists made at this shop are aromatic, sweet, crunchy and crisp. Guifaxiang dough twists are also sold in Food Street. Each of the dough twists weighs about two or three pounds. They are appetizing in colour and fancy in shape.
