I am from Shenzhen.
When you eat seafood in the urban area, you usually go to the Seafood Food Street in Paradise Road, Luohu District. That street is full of seafood restaurants, and the result of fierce competition is relatively flat and beautiful. Recommended Huacheng, which has been eaten for 20 years. There are many Tewang people near the gate of Luohu Cultural Park, and seafood pool is at the gate. The price is relatively affordable, but the quantity is definitely insufficient. Personally, I think seafood here is the cheapest and most affordable.
Generally, Yantian is near Yantian Seafood Food Street, which is fresh enough and not cheap.
There are many seafood restaurants in Shuitou, South Australia. The shops there only process seafood, which is bought at Shuitou Seafood Market. Not very good reputation. There is also a row of seafood restaurants in South Australia, which are fresh, but more expensive than those in the city. Individuals feel that they are engaged in tourism business.
Locals all know that eating seafood depends entirely on the conscience of the store owner. For example, if you order a kilo of shrimp, it&;s definitely not enough for you to serve it. There is nothing short, just something that is relatively less pitted and relatively standardized.
