Matchbox, an East Coast chain that opened its first Texas location at the corner of Walnut Hill and Central Expresway, is introducing the city to Washington, D.C.-style pies. Yes, Washington, where people know how to get their hands on a slice of the pie, even if they can’t agree on the toppings. Sliders are a Matchbox specialty. Choose three as a meal or more as an appetizer for a big table. With toasted, buttered buns and well-seasoned meat, the sliders are high-quality. Signature pizzas are very good. Crust is thin, but not too thin, and Matchbox opts for a chewier style rather than the crispness of Roman-style pies.
