Are you looking for TS or QS?
In Epcot, we really enjoyed the Akershus breakfast for a sit down character meal, but I also have a princess crazed DD. For QS, I really liked Sunshine Seasons in the Land Pavillion.
At DHS, for QS, Starring Rolls has some awesome pastries. I can't help you with TS. I think the only TS restaurant in DHS offering breakfast is Hollywood & Vine and I've read really bad reviews of it.
