As a native of Guiyang, I think the best sour soup fish is the "old Kaili sour soup fish" located near Huguo Road in Nanming District. The sour soup fish in this restaurant tastes authentic, fresh and tender, moderately hot and sour, and is very appetizing. Besides, their Qianjiang pork knuckle rice and spicy crispy fish are also worth a try. Besides, if you like hot pot, you can try the "Old Wharf Hot Pot" in Yunyan District. Their hot pot tastes rich, the dishes are fresh and their reputation is very good.
