Yes, the Crab N is great! They will cook your fish for you as well. When you walk in the door they will take your fish to the kitchen and then when you order, you just tell them how you want it cooked. There are 3 or 4 good options and it always seems like more fish than you brought in!
Wherther you bring fish or not, Crab N is and has always been my favorite place to eat near Rockport/Fulton/Aransas Pass.
