McDonald's does not serve lunch before 11 or 10:30. The rationale used to be that eggs and burgers need different temps on their grill, but now that they serve all-day breakfast I'm not sure what they do. Regardless, mornings are still breakfast-only. Burger King does actually serve lunch at all hours. Wendy's doesn't open until 10, and doesn't have a breakfast menu. Taco Bell does has a separate breakfast menu. Most of their stores now open at 7, and they start serving lunch items at 9. They stop serving breakfast between 9 and 10.
