Part brick-oven pizza place, part takeout joint, part grocer, and altogether an easily missed-yet-worthwhile sit-down restaurant, Giorgio’s is a small-sized establishment that lets its food do the talking. “FUHGEDDABOUDIT” reads the awning outside this 17th Street eatery that sits in a low-key strip of buildings, and they’re likely referencing the fare at other Italian institutions in the area. That’s because Giorgio’s takes pride in its pizza, pasta, and pomodoro-packed plates. Lunch specials really are special, such as the grilled chicken and broccoli rabe sandwich with sauteed cherry peppers, garlic, and melted provolone, and the mussels Romanesco steamed in marinara sauce with diced tomatoes, onions, garlic, herbs, and a splash of cream. Save space for tiramisu and cannoli.
