For the most part, Dragon Pizza in Davis Square looks like any old slice joint with grease-stained tables and paper plates. But the extensive collection of cassette tapes on the wall should clue you into the fact that this place is a little different. The pizzas are definitely a step above what you’ll find in most slice spots, like the plain cheese that’s perfectly blistered, and a maple BBQ slice that’s better than it has any right to be. Even the salads here are solid.
