Food trucks and trailers can be a great place for operators to test out a concept with relatively low overhead, as well as a nice change of pace for diners looking for value and creativity. Or maybe just some solid food to help soak up some beer. A few of these places have since gone on to also open brick-and-mortar restaurants, but I'm including them in this unranked list because they're still darn good at doing what got them started. You won't find tacos or barbecue here; they will get their own best-of lists in our annual Dining Guide, which publishes Oct. 21.
