CapMacDC: Mac & Cheese On Wheels

Run by chef Brian Arnoff, who has worked under Barbara Lynch in Boston and for one of Michael Mina's establishments in D.C. describes his wandering food truck as "The Capital of Macaroni." Mac and cheese is thus, not surprisingly, the main draw here, either in classic form or with meatballs or "sloppy" with meat sauce. There's also long-cooked brisket over rigatoni, Buffalo chicken mac, and a "happy ending" bar — a layered concoction involving a chocolate chip cookie, a coconut brownie, and a sheet of honey walnut toffee.
