A trompe-l'oeil ceiling adds space and light to a simple interior at the ever-popular Pizzeria Paradiso, which has spinoff locations in Georgetown and suburban Alexandria, Virginia. The restaurant sticks to crowd-pleasing basics: pizzas, panini, salads, and desserts. Although the standard pizza is satisfying, you can enliven it with fresh buffalo mozzarella or unusual toppings such as potatoes, capers, and mussels. Gluten allergies are accommodated with special dough, available on request. Wines are well chosen and well priced. The intensely flavored gelato is a house specialty.
