Papi Queso shook up the local food-truck scene with its focus on grilled cheese sandwiches featuring fancy add-ons such as braised leeks, green apples, and barbecue. As with most food trucks, the menu constantly changes, but one always-on-offer standout is the truck’s truffle kettle chips. Made fresh with rosemary, shaved Parmesan, lemon, and white truffle oil, the crunchy, decadent chips are reason enough to track down this restaurant on wheels.
