At the Main Street Tavern, the mozzarella stick has finally grown up and gotten some class. The mozzarella-and-prosciutto spring rolls here put real mozzarella, thick-sliced prosciutto and whole basil leaves inside a crisp spring roll skin for an updated, mature take on the late-night bar-food classic. The rolls come out piping hot, gooey and deliciously salty thanks to the prosciutto, and because no one should ever fuss too much with a proven favorite, each order comes with a little dish of plain, slightly spicy red sauce for dipping. Sit back, call for another round, and enjoy.
