I adore Franktuary (in Lawrenceville) and their food truck is just as great! The staff are friendly, and your food comes out hot and very fresh. On the particular day I visited, the guys working the truck took pains to check on the ingredients in the hot dog buns so I could avoid dairy and provided me with wonderful service overall. I will be back anytime I see them parked at an event. (FYI, they take cards.)
