Fortunately this is not a food review but a rather weird observement. Since I've bought a condo in Midtown, I occasionally drive down the old 10th street cooridor between downtown and I-44. Every weekend and some weeknights there are what I call "Taco Vans" on the corner of NW 10th and Penn and another one in the Whittaker's parking lot on 10th and May. They are big vans (similar UPS style trucks) selling taco's out of a window in the back of the truck. Weird!
