Okay, we may have been joking in the Groundlings Restaurant Film, but a recent US study looked at seafood menus going back about 150 years and showed they reflect the increased scarcity of seafood. But even better than this to show it (and I wish I had photos of this) is the story of my British friend who sent me the link -- he says he can remember in the 1960's when you would order turbot at the best seafood restaurants in London and they would bring you a big crosscut of the popular fish. Today, they'll bring you the same amount of fish, but now its a lengthwise section of the fish.
What's (left) on the menu?
