There's Mimi's Cafe across the street.........IHOP.......and Original Pancake House up on Lincoln just East of East Street but before State College.....
.....go a little further, there's Watson's Drug Store in the Circle in Orange...a bit of a trek from Disneyland, but if you're up for it, it could be fun. They shot scenes of "That Thing You Do" with Tom Hanks/Liv Tyler, there.
The original (and only one left) SAMBO's, oh no, that's way up in Santa Barbara.
For breakfast I just usually have a quick Egg McMuffin, or have donuts and oj in my room while getting ready. That way I dont have to get up earlier just to wait for breakfast in a sit down restaurant.
