Family is one of the customer types in Diner Dash series. They are first introduced in Diner Dash 2: Restaurant Rescue, which consists of a father and a mother with two children, one of which is a baby.
Families are all-rounded customer types as they order and eat at a moderate speed. They leave moderate tips as well. However, special attention is needed when serving family customers. Firstly, a high chair is needed for the baby. Otherwise, the baby will cry and upsets other patrons. They are also prone to making spills on the floor, so Flo has to pick up the mop to clean their table. If a bar counter is included some levels, Families are not recommended to be seated there as the high chair cannot be placed at the bar.
In later series, families consist of a mixture of different characters. For example, father and son, two mothers with babies and so on. Sometimes even a senior is included in the family group, but there is no indication in the canon that they are somehow related.
In other spin-off games, each family member is given a name and have developed personalities:
