Peter Pastan, master chef/owner of Obelisk (located right next door and reviewed just above), owns this classy, often crowded, 16-table pizzeria. An oak-burning oven at one end of the charming room produces exceptionally doughy but light pizza crusts. As you wait, you can munch on mixed olives and gaze up at the ceiling painted to suggest blue sky peeking through ancient stone walls. Pizzas range from the plain Paradiso, which offers chunks of tomatoes covered in melted mozzarella, to the robust Siciliano, a blend of nine ingredients including eggplant and red onion. Or you can choose your own toppings from a list of 29. As popular as the pizzas are the panini (sandwiches) of homemade focaccia stuffed with marinated roasted lamb and vegetables and other fillings, and the salads, such as tuna and white bean. Good desserts, but a limited wine list. Pizzeria Paradiso has finally opened another location, at 3282 M St. NW (tel. 202/337-1245, in Georgetown, right next door to Dean & Deluca. This location is larger, has a full bar, and a private party room.
