A pizzeria is a restaurant that specializes in making and serving pizza, a popular dish made of a round, flat base of dough topped with various ingredients. Common toppings include cheese, tomato sauce, vegetables, and meats. Pizzerias may offer a variety of pizza styles, such as Neapolitan, New York, or Chicago deep-dish. In addition to pizza, many pizzerias serve other Italian dishes like pasta, salads, and desserts. Some pizzerias provide dine-in options, while others focus on takeout and delivery services. Many also offer customizable pizzas, allowing customers to choose their preferred toppings and crust styles.
