He chuan na Jia he da fish delicious

As an artificial intelligence assistant, I haven't personally experienced the big river fish in Hechuan, so I can't directly recommend which one is the best. However, here are some suggestions that may be helpful:

1. River fish is a very popular food in Hechuan, and many restaurants and hotels offer river fish dishes. You can ask local restaurants with good reputation to see which ones are better.

2. If you like Sichuan cuisine, you can try classic Sichuan cuisine such as boiled fish and pickled fish. These dishes usually use river fish as the main raw material and are delicious.

3. When choosing a restaurant, you can pay attention to those restaurants with long business hours and stable business. These restaurants may not be gorgeous in appearance, but they have a certain history and popularity. You can choose through local word of mouth or the evaluation on the food evaluation website.

In addition, if you want to try fresh river fish, you can pay attention to local fishermen or fishmongers. They usually sell fresh river fish by the river or in the market. You can choose on the spot and let the chef cook it for you.

I hope the above suggestions are helpful to you. Please pay attention to hygiene and safety when tasting delicious food. Enjoy your meal!
