Brad Pitt and Angelina Jolie take their six children to Arris' Pizzeria when they visit the actor's hometown of Springfield, Missouri, and let the kids ''raise a ruckus''.
Brad Pitt lets his kids have food fights in restaurants.
The 48-year-old actor takes his six children - Maddox, 11, Pax, eight, Zahara, seven, Shiloh, six, and four-year-old twins Knox and Vivienne - to Arris' Pizza whenever he and fiancee Angelina Jolie visit his hometown of Springfield, Missouri, and the eatery closes to allow the famous family some privacy.
A source said: ''The place shuts down for the entire night and the kids raise a ruckus.
''They jump on tables and even throw food at each other!''
Although the children are not accompanied to the pizzeria by their nannies, Brad and Angelina, 37, go along too but seem to staff unconcerned about their kids' antics.
The insider added to Us Weekly magazine: [They] let the kids enjoy themselves. Brad and Angelina just sit there and talk to one another while the children run around in circles!''
The family recently spent time in Littlebourne, Kent, South East England, and were said to have been ''beautifully behaved'' when they visited a local post office to send letters to Santa Claus.
Post Office assistant Fiona Lindsay said: ''It was so cute. All the children sent messages to Father Christmas and were absolutely beautifully behaved.
''Just like any other kids in a sweet shop they were excited, but Angelina controlled them perfectly. [Angelina] was so polite and a really nice person. I was quite shocked at first but Angelina was so lovely I soon relaxed.
''The children bought a packet of sweets each, plus a few toys and some magazines, and we ended up having a general chat about how they all were and what they were going to eat that night.
''It was lovely. They were all very polite. They were just a bunch of gorgeous, happy kids.''
