Tucked beneath the elevated 7 train subway platform in Sunnyside, this tiny sit-down diner serves a wide array of bang-for-your-buck dishes, plus destination-worthy donuts. The all-day menu features everything from three-egg omelettes and full Irish breakfasts to chicken souvlaki and tuna melts. Made fresh daily, the donuts are so light and fluffy that you almost need two (or three) to fill you up. Craving a cruller at 3am? Alpha's got you covered -- it's open 24 hours.
