Traveling eateries lack the whimsy of a traveling carnival, but rarely result in cotton-candy comas or accidentally winning a Saddest Clown Face competition. Support smile-touting trekkers with today's Groupon: for $4, you get a signature sub (a $6 value), a soft drink (a $1 value), and a bag of chips (a $1 value) from Sub Urban Bros (an $8 total value), a sandwich truck based in Rockville.
D.C. burb natives Rick Baldwin and Shane Patterson concoct and convey a menu of signature subs from within a retired U.S.-mail-truck-turned-traveling-taste-factory. Snag one of Mama Toni's Meatballs, smothered with marinara sauce under a sheath of provolone cheese, at a conglomeration of neighborhoods, businesses, sporting events, and Roosevelt look-alike competitions. The JK sub quells carnivorous cravings with an amalgam of turkey, ham, and bacon beneath provolone, and the veggie fulfills garden fare fancies with mushrooms amid a mountain of american, swiss, and provolone cheese. Restaurant-weary tongues can tantalize taste receptors with extra toppings such as mushrooms, bacon, a medley of meats, cheese, and pepperoni ($0.95 each), or step up to the sub-stamped, flame-painted truck for a bag of chips and a soft drink to foolishly throw at the fiberglass flames before shamefully retreating.
