A restaurant called Kai Mayfair in London sells a specialty soup that contains Japanese flower mushrooms, sea cucumber, huan ham, chicken, dried scallops, abalone, shark fin, ginseng, and pork. Don’t expect to be able to get it when you walk in the door unless you ordered it five days before your visit, however, as it takes a while to get some of the ingredients. I somehow wouldn’t be surprised if the chef wrestled the shark themselves.
