Every time I see a story like this, I'm reminded of that scene in the Fifth Element with the flying car/boat Chinese delivery and (I'm guessing) mobile restaurant.

Still bitter about not having flying cars yet, but I don't necessarily see the mobile service as anything bad. It's just the natural progression of the food cart, some of which, are exceptionally good. In New York, there's a Halal cart on 53rd and 6th and everyone from construction workers to Wall Street types wait in line... and it's all worth it!
