One of my favorite recent foodie discoveries is the Thai Elephant Food Truck plying the streets of Montclair NJ.
The nature of Thai Food is that everything is fresh, preparing in advance, or even using frozen items just doesn't work. That tradition continues here.
Anyone who has run up to the truck as it arrives at a new location knows all too well that there is about an 8 or 9 minute wait from the time the truck parks until the first food can start to be served. There's peeling, and chopping, and dicing that is done just before the actual cooking. Of course everything is cooked to order so once that initial preparation work is done, the longest I've ever had to wait for an order was 2 minutes. And it's so worth that wait.
