Realize that since the McD is on WDW property its more expensive than your local McD. There is no value $1 menu at this location. We've bought food there because we were at MK til 1am and the McD is opened 24 hours a day. Allstars food courts close at midnight. I think its busier too because of people wanting coffee other than the Nescafe that Disney sells.
We grab breakfast at the Main Street Bakery, Bagels, fresh fruit or be bad and grab a cinnamon roll (its huge, DD14 and I split it and didn't finish it all) Not bad for $2.29.
Right after 9/11 the characers used to go to the resorts on selected days because Disney did away with extra Magic Hours. Now that they have them again no more characters at the resorts.
