Where is it cheap to eat seafood in Qinhuangdao? how much is it?

If Qinhuangdao likes seafood, it's best to stay in the city. On Saturday night, I went to Donggang Road Market to buy seafood, and bought one and a half Jin of Pipi shrimp (10 yuan/Jin) and four crabs (25 yuan/Jin), 50 yuan. Then go to the Donggang Hotel near the intersection of Hebei Road and Donggang Road for dinner. The hotel is responsible for processing seafood itself, and the processing fee is only five yuan. The specialty of the hotel is washed mushrooms, which is much cheaper than similar restaurants in Beijing. What we want is the cheapest set meal in 88 yuan, including black-bone chicken pot bottom, five kinds of mushrooms, three plates of vegetables, one plate of mutton and one portion of noodles, which is enough for three or four people. Absolute value! Win by quantity on Saturday, and eat something good when you are full on Sunday. There are several large seafood restaurants on the beach near the place where Qin Huang invited immortals into the sea. We chose Donggang Seafood Plaza. The restaurant environment is good, and the seafood price is not expensive, such as sea urchin 5 yuan/one, scallop 8 yuan/one, scallop sashimi 18 yuan/kg, sea urchin, all kinds of fish and so on. Unfortunately, there are only two people, so I dare not order too much. Next time!
