If there was a category CL's Best of Charlotte issue for "fish," Clean Catch would win hands down. As far as I can tell there is really no competition.
The old adage, "you get what you pay for" holds true here, so be prepared to pay for your seafood. Sure, you can save some money by buying your swordfish steaks at Harris Teeter, but how long have they been sitting there? If you don't mind a piece of fish that is discolored and tough, go ahead and save a bit of money. But if you want the freshest, most beautiful piece of fish in town, you should shop at Clean Catch Fish Market.
I visited for the second time yesterday and purchased about 14 ounces of marvelously pink sashimi-grade salmon and about 6 ounces of kajiki (blue marlin) that we turned into a beautiful tartare.
