In a few days I'll be buying some fish: cod and salmon, specifically. I'll need to buy whole fish as opposed to filets or pieces. I've bought quality halibut at Fairway, but it wasn't whole. What are your opinions for excellent fish markets where one can buy whole fish? Do you think Chinatown (eg Mott, saaaaay near Elizabeth) is a better bet than a supermarket? I live in Columbia territory, so markets in Harlem/UWS/thereabouts are a plus.
