Many Italians still enjoy the family tradition of the Sunday lunch - il pranzo della domenica. It is a happy occasion to meet with the whole family around the table and eat while catching up and gossiping. Traditionally, families meet at mamma's because her cuisine has the magic power of bringing us back to our childhood years.
In Italian more than in any other language and culture the expression "there's nothing like mamma's food" is true, but nowadays many families have decided to give a break to mamma, at least on Sundays or on big family celebrations, and treat her at the restaurant to allow her to enjoy the meal too.
