A trip to Belgium inspired Fryborg, a new food truck that specializes in hand-cut French fries with homemade dipping sauces (curried ketchup, pesto mayo), grilled cheese sandwiches, and 25 flavors of real-sugar sodas in glass bottles (no fructose here!). Chef Jon Gibbons will cater parties from a simple snack to lunch or dinner, for $5 to $25 per person. Most requested? Grilled fluffernutter sandwich with bacon and buffalo chicken fries.
