1900 Park Fare (atleast dinner, usually breakfast also)
50's primetime cafe
Sci-fi
pecos bills (we like the condiments bar- especially the mushrooms LOL)
Donalds breakfastosaurus at AK
Beaches & Cream
Whatever that "market" is called at CSR? I can't remember the name but we usually eat there atleast once each trip. Weird how I can't remember the name...
Those are the regulars for us in the past. We've tried some different places this last trip (Crystal palace, Chef mickeys, Ohanas breakfast, etc.) and I think our "regular" list is going to have an addition:
Ohana (Stitch/Lilo) breakfast (oldest is major stitch fan... food wasn't that great though)
In the past Rainforest Cafe was a regular for us but then we figured out we have one "kinda" close by (about an hour's drive, but we're used to long drives where we live) here locally- so we go there quite often and thus don't need to do it at WDW.

It's exactly the same here as it is at AK & DTD! Added this note because if there wasn't one near us- we'd still be going to Rainforest cafe at WDW each trip!
