I havent been either since the new breakfast changes but from reading here and another forum,
1. The main breakfast in the park is at Cafe Hyperion. This is where people on the free dining plan go for a quick service breakfast. Depending on park capacity I have also seen people say Pizza Belle Notre and Cable Car Bakery are also open. Im sure you can pay for breakfast at these places if you dont have the meal plan vouchers.
2. There is a character breakfast at Plaza Gardens.
3. In Disney village places like Starbucks, McDonalds, Earl of Sandwich open at 8am
4. There are also now Starbucks at some of the hotels, Santa Fe and Cheyenne I think, possibly others
5. You can always go over to Val d'Europe and get food there
