McDonald's serves breakfast foods until 10:30 a.m., and doesn't start serving regular meals until after 10:30 a.m., when it stops serving at 12:00 p.m. This is basically standardized across all franchises, whether they are open 24 hours or not.

McDonald's is a large global multinational restaurant chain, founded in 1955 in Chicago, USA, with about 30,000 outlets around the world. It mainly sells hamburgers, as well as french fries, fried chicken, sodas, ice, salads, fruits and other fast food.

McDonald's restaurant in mainland China in the early translation of the name is "McDonald's fast food", until the later part of the unified use of the current Hong Kong-style translation of the name. In the private sector, because of the similarity between McDonald's and "Peony House", Peony House is also taken as a nickname for McDonald's, but it is not common.
