Sosta Pizzeria is the little pizzeria cousin of the tonier Quattro Gastronomia, also on Lincoln Road. Outdoor tables, sheltered by oversized orange umbrellas, are generally packed with beautiful people and the small dogs who love them. There are over two dozen pizzas to choose from -- all thin crust, baked in a wood-fired oven and generous enough for two. The Rustica Pizza served with goat cheese, tomato, roasted peppers, and Italian sausage ($12) and Siciliana with anchovies, black olives, capers, and mozzarella ($11.95) are favorites. Salads are available in appetizer and dinner portions, in case you want to skip the pizza to better fit into your teeny bikini. Service ranges from slow to non-existent, so be prepared to sit for a while and enjoy the people watching.
