Yum Yum Donuts has become a Southern California institution. It was the first donut shop to stay open 24hrs and bake its pastries on the premises, so that there would always be a supply of fresh baked goods. This Yum Yum is located in the Valley Plaza shopping center. It recently added breakfast sandwiches to its menu, where bagels and croissants are filled with eggs, bacon and sausage. It also serves fresh brewed coffee and also offers soft drinks, juice and milk. It has a variety of donuts, using cake and glazed dough, with an assortment of icings and sprinkles. It also has filled donuts with both cream and fruit.
