This was my #2 takeaway from Disneyland, after #1 being so impressed by how their Fantasyland is set up (truly making you feel like the characters live there and you are just wandering around finding their attraction homes).
It was just amazing how much good, fresh food with a nice variety was available - and the hours they were open. For being a place where so many people are captive, WDW has always had pretty lousy food availability hours. At Disneyland, multiple places serve food from the time the park opens (like, actual quick service breakfasts that aren't just pastries), until they close. That was one of the many reasons that even when I went to WDW regularly, I wouldn't go without my own vehicle - if it's 10PM and you are hungry after leaving the park or at the resort, you basically have to eat out of vending machines.
