Hi
I know that the Main Street Bakery has some breakfast stuff. I've only gotten a cinnamon bun there. You could look at allearsnet.com and go to the menus and check out what the parks offer for counter service breakfast.
Can't remember about the other parks, but do not eat CS breakfast in MK! The bakery is good, but I swear it is THE ONLY place in the park open until like 10:30am! So crowded!!! When we do early MK we just grab something from our room.
I think the place in the Land in Epoct had some good breakfast things.
WE had breakfast at the ABC Commissary at DHS last Feb, it was pretty good. We split the breakfast platter, I'm thinking it was bacon, sausage, scrambled eggs, potatoes and a biscuit? It was about the same as the breakfast platter at Pop and CBR.
