Ran into these guys at today's Sunset Park'd food truck festival and concert. Chose the Whack Job sub ($7), which was basically an Italian sausage with coarsely chopped peppers and onions.
I'll tell ya, it was pretty whack how the sausage felt so small in comparison to the dull bun that it was subbed it. It tasted pretty good, but I would've preferred to pay more to get a better meat-to-bread ratio. Some sort of sauce would have helped too, or maybe serving the peppers as a giardiniera instead of just sliced and grilled.
Friends weren't overly impressed with their burger (forgot the name but it was the one with the balsamic), so if you're going to try these guys, pick something else, like one of the mozzarella-topped sandwiches.
