I don't know DC at all. Will be in town this weekend and am staying near convention center. Saturday night I'm going out with friends. If this is possible, I would love to eat something remarkable and creative at under, say, $40 per person and within, say, a 10 minute cab ride. Something not bland or French, something flavorful and interesting. Asian, Mexican, South American--any or none would be acceptable. Doesn't have to be fancy, just interesting food. I'm in your hands: where should I eat?
