Kushisei is a grilled seafood stall in Kuromon Market in Osaka that sells king crab legs and scallops. King crab legs are grilled to order on site, and the scallops are cooked with butter. The stall is run by a family and offers several sauces, and takeout food has to be eaten in front of the shop. The market has no bins, so you need to bring something to put your trash in.
