Have to meet someone for morning coffee at Columbia and I wanted afterwards to go for my favorite foods: tripe or tongue. The simpler and cheaper the better: tacos, simple tripe soups, and so on. Latino, Asian, and so on -- any preparation would be fine. Any recommendations?
Oh, and quick (i.e., not a long, sit-down meal) would be preferable too. But it should be a place where one sit rather than, say, take-out from a taco truck.
