Sexton's for shrimp. No credit cards, though. Cash or local check. The service there is a little curt and not particularly friendly, but their shrimp and fish are very fresh. I like Destin Ice for more of a full-service seafood market. Their prices seem to be a tad higher on fresh fish and shrimp, but if you're intimidated by fish in particular, they're a lot more helpful, and they also carry a lot of prepared items. I haven't tried Blalocks. HTH!
