King crab legs are different story.
You should take a cruise on Caribbean Princess - they served Alaska King Crab legs 3 out of 7 nights at the buffet area - 1 cold seafood night, 1 hot seafood night and 1 night it was one of many other dishes served. In dining room the Alaska King Crab leg was on the menu one night, but I ordered the Rack of Lamb that night. 2 guys on a table across from ours, had the crab legs and boy, they must have had at least 20 legs between the 2 - the shells were piling up like a small hill on their table!
