Family practice
Pizza as a common birthday and celebration food
In the United States, United Kingdom, and other pizza-eating cultures, pizza is one of the most commonly chosen foods for children's birthday parties and informal celebrations — valued for being easy to order in bulk, agreeable to a mixed group of children and adults, and requiring no seating plan or plated service. This is a contemporary social convention rather than a historically old one: pizza's role as party food tracks its broader mainstreaming in the postwar United States rather than predating it.
