Them Alaskan king crab brings in a higher pricing than our D crab. I loved to eat them the same.
I do not think it is a good idea to only eat them crabs at the buffet. I mean if you eat to get your money's worth mentality then sure, you'll feast on it until you come up on top. I've done that before and I got toxic poison. Even shingles, if it is what it is when the body goes into hives and itches all over.
I do not have seafood allergy but when I had my brush of death, it brings my spider senses back to earth. I will no longer eat my money's worth.
