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. Customers can often choose to dine in, take out, or have their food delivered. Pizzerias are popular gathering places for families and friends to enjoy a casual meal together.
