Take a taxi to barbecue. Generally speaking, it will not exceed 10 yuan. There are many barbecue shops in Jinzhou with various grades. You can ask the taxi driver to recommend one as appropriate. I think there are also old white barbecues and chicken feet.
There is nothing you can do about it. You'd better find a place to cook it after you buy it. You can go to Bijiashan to buy it, and then negotiate with nearby stores.
The bus route to Bijiashan is monopolized by Tiger Leap, so you can take a taxi if you don't want to take it, so it is recommended that you take Tiger Leap on the left for at most one hour.
There seems to be nothing on Bijiashan Island except temples. You can play with water from the foot of the mountain and take the overpass, that's all. Jinzhou section of Liaoning Binhai Highway has been repaired. It's good. If you have time, you can take a walk along that street. There are also three sea-crossing bridges. The roadside is the sea, and you can pick up things to play with when the tide is low.
Bijiashan Bath is free and can enter the water.
Tickets to Bijiashan 40 yuan, about 10 yuan/person by speedboat. I can't remember clearly that the ebb and flow of the tide depends on the date. You can consult people nearby.
