Wall Street Journal had a piece about small restaurants like Momofuku Ko in NYC, Cage Atlantico has the Andre's Minibar in Washington. The cost for minibar is $120 (without tax, drink). You get a constant "flow" of food.
Ko does not have a sign. There only 12 people at a counter and you have to reserve sometimes a month in advance. You don't get bread, and there is no menu. You eat by sitting on a stool! Most servings are served in bowls.
Some of the recipes that came to this editor were: shaved foie gras atop lychee; lasagne with escargot and porcini mushroom and ricotta. Small plates and odd ingredient recipes and more are the norm. Definitely for some people.
