Imagine waking up at 2 a.m. with an insatiable craving for a fresh, crisp head of lettuce and an empty refrigerator. Since 1990, Rossman Farms has erased such nightmares. Nestled beneath the BQE overpass, the Third Avenue store stays open around the clock selling peppers, melons, tomatoes, squash—pretty much every type of produce except the pizza fruit, which is still confined to dreams. The almost-overwhelming selection occupies the first story of an old warehouse, welcoming guests into a colorful world that also includes spices, coffee, and other dry goods.
