A pizzeria is a restaurant focusing on pizza.
Many pizzerias offer take-away, where the customer orders their food either in advance or at the restaurant and then takes the prepared food with them in pizza boxes to eat at another place. Many pizzerias even deliver food to the customer's home, where a courier transports the ordered food to the customer's outer door or to another agreed site, provided that the delivery address is within a suitable distance from the pizzeria. Pizzas can be transported by car, but in many countries pizza couriers deliver by bicycle or moped. The food can be ordered at the restaurant, by telephone, or by Internet.
In Italy, pizza was traditionally food for the poor and thus contained few and cheap ingredients. As pizza became popular in the United States after World War II it became mostly a practical dish that was quick and easy to prepare, not so much food for the poor any more. Pizza was not especially expensive, but the number of ingredients increased and pizza was no longer made simply from cheap ingredients. Pizza became even more accessible when frozen pizzas and pizza delivery were invented.[1]
