Since at least the era of nouvelle cuisine, the theory that the price of a dish increases in reverse proportion to its size has been all but mathematically proven. Ergo, happy hour at The 9th Door must constitute a time warp—because from 4:30 to 6:30pm, this downtown tapas bar turns out small plates like aceitunas rellenas (deep-fried, tuna-stuffed olives), honey-drizzled goat cheese, and tostas truchas, or smoked trout spread en croute, for a measly $2-$3 each. And since food consumed in a rent in the time-space fabric doesn’t count, you won’t even spoil your dinner. That’s a scientific fact.
