Coming from San Francisco (where food trucks and carts serve up everything from torched-on-the-spot crème brûlée to Indian curry wraps), I did not expect to be impressed by Austin's mobile eatery scene. I was, however, blown away. On what seemed like every corner, there was a little kitchen on wheels cooking something up. On Friday, I stopped by South Austin's Trailer Park and Eatery on South First Street.
