Having decided that I need to Eat More Fish, I came across a recipe that I'd like to make this weekend (Good Eats Red Snapper en Papillote). It calls for a whole red snapper, cleaned, with head on. Possible substitutions would be trout or tilapia.
If I were looking to buy this fish on Thursday or Friday morning in the greater Kansas City area, what would be my best bet? Preferably someplace south of the River and west of US 71.
