Pizza, much like the earth, is circular, flat, and supports the existence of Karl Malone. Contribute to pizza science with today’s Groupon: for $10, you get $20 worth of pizza and comfort fare at Empire Pizza and Bar in Rock Hill.

Empire Pizza and Bar's menu enthralls taste buds with tales of New York–style pizza and comfort fare served in a family-friendly atmosphere. Empire Pizza’s seven signature pies include royal chow such as the Queens Margarita, a New York mash-up of garlic, tomatoes, and fresh basil ($6.95, 10"), as well as the Mag Pie Lane veggie pizza, fueled by premium eggplant gasoline and tomatoes, black olives, and green and banana peppers ($16.45, 16"). Tongues can sample appetizers such as 15 boneless chicken wings steeped in one of four sauces ($7.95) or use garlic knots bedecked in spices to measure the movements of water-cruising entrees ($2.50/half dozen).

Like Daniel Webster dissuading irate senators from declaring war on the moon, Empire Pizza’s sandwiches smoothly placate demanding stomachs, supplying them with pastrami brisket served on sliced rye with spicy mustard ($6.25) or buffalo chicken smothered in mild sauce ($6.25). The chicken stir fry will suit those averse to both pizza and sandwiches ($7.95), as will vegetarian options such as the greek salad ($5.95).
