Good Advertising?

Here is a picture of an outdoor eatery at the Gangjin Celadon Festival. I've noticed that many restaurants place animal legs, hides, or live seafood at their entrances. I assume that the legs prove the meat's origins and that the seafood shows freshness. Perhaps these items even attract people to the restaurant. As for me, I find myself wary about eating meat when I see a squashed carcus.
