This is an interesting concept - just for February, the Little Bay Restaurant in London is letting diners eat their meal and then pay whatever they think that meal was worth... including nothing (excluding alcoholic beverages). I think it's probably not a bad idea in theory - I'm definitely willing to pony up for a wonderful meal. But the problem lies in maybe not realizing how much a meal
is actually worth. If I had duck salad, which is one of the items on the menu, I would have no idea what the going price for duck meat is, so I could potentially be totally stiffing the restaurant without intending to. At any rate, it's definitely getting the restaurant some free publicity... which is probably the point.
