About five years ago at Phil's Fish Market in Monterey CA. They serve up five-pound Maine Lobsters to order. Cost a fortune, but well worth it.
Also well worth it are the Alaska King Crab. Sweeter than lobster.
On that same ilk, the Australian Lobster, also called the Morton Bay Bugs, are also a great meal. They are small, so it takes about eight of them to make a meal. But their meat is sweeter than the Maine Lobster, but not so much as the crab.
