Diana used to bring William and Harry to the pizzeria for lunch, and now there are several reminders of her custom. There's a six-foot-high oil painting on the wall and Pizza Diana on the menu, made with four different cheeses and an artichoke heart. Da Mario is also where Renée Zellweger ate out to gain weight before the first Bridget Jones movie, as she was staying in a flat nearby. The actress would apparently order pizza, garlic bread, and beer.
