As part of my trip to Vancouver (partially to watch its international fireworks competition), I did much research via chowhound, Vancouver Magazine's restaurant awards, Fodor's discussion boards, and other web sites on good restaurants within the city.
Go Fish, from what I read, felt like a local dive. It has no web page and no real building. I knew I had to go.
Go Fish fulfilled its reputation, serving me perfect fish and chips.
I ordered two pieces of halibut. These were hot and perfectly breaded but still moist, a nice contrast to the overcooked halibut at Chambar from last night. Two was definitely too much for me, but they were addictive and I couldn't stop. (I hoped I could walk off the calories later in the day... I did walk a bit, though certainly not as much as the previous day.)
The fries were similarly perfect. And I don't use that word lightly.
The spicy coleslaw was fairly good as well.
As for decor, Go Fish is a stand near the water. And it's indeed as popular as I imagined.
