Fish shouldn't smell fishy. Not the ones you're going to eat, anyway -- not if they're fresh. And by extension a fish market shouldn't have a questionable aroma, either. That's why I was pleased to smell absolutely nothing besides the salt water from the live Maine lobster tank when I walked into Mr. Fish (2781 E. Atlantic Blvd., Pompano Beach, 954-941-3275). The selection is enormous -- swordfish, tuna, flounder, dolphin, yellowtail -- and changes daily, according to what's coming in fresh. As for crustaceans, you can count on king crab legs, snow crab clusters, cleaned soft shell blue crabs, and rock lobster tails. Even with all this seafood, the only assault to the senses comes from the exhaust of the cars rumbling by on a nearby street.
