Restaurants in Chinatown have those tanks of live fish, but is there anywhere I can choose a fish, have it cleaned and take it home to cook? I have a family recipe I want to try out that calls for live fish (my aunt says it just won't be the same if I use frozen, so here I am on the hunt).
Super 88 Market located at 795 Eastern Ave (Route 60) in Malden has live fish in tanks. You can pick out your fish and they will clean it for you. I haven't bought fish at Super 88 but have seen people buy their fish. I've seen tilapia, catfish and other kinds of live fish.
My favorite place is Kam Man Center in Quincy, followed by C Market in Chinatown.. I have not had great luck with the tanks at the Super 88, in Allston or South Bay. The fish often tastes muddy, or of urea, becasue they don't keep their tanks clean enough, IMHO. I bought a tilapia last night, and even with the Sichuan sauce i simmered it in, you could still smell the less than pleasant aroma.
