I just try a local Fish and Chip place not far from the house. Sometimes good things are close to home.
Al's Fish and Chips
2139 Roosevelt Ave
Redwood City, CA
They have freshly fried fish and chips as well as deep fried fish tacos not cheap at 3 buck apiece. But they have a local flyer that gives you buy one get one free.
My nonchowhound son found this place when he came home with deep fried squid (not frozen but freshly battered) topped with fresh garlic. A lot for 7 bucks.
So far we have only fish and chips, fried squid and the fish taco. There are a lot of other items. Worth a try if in Redwood City, not in San Freancisco.
