These are our faves and least faves
Most QS portions are enough for 2 people to share, especially if it's warm, so you can spread those out if you want to try lots of different places.
Our most absolute favorite in the whole world is Boma at AKL, breafast and dinner. Also our favorite resort and well worth seeing.
MK - Liberty Tree Tavern, but be prepared for a pretty long wait past reservation time. Worth it, though
AK (best food here!) - Yak and Yeti QS and Restaurantsaurus, we also really like Tusker House which has a menu very similar to Boma, fewer offerings but it's a character meal so it's a trade off. They also offer lunch, which Boma does not.
HS - we enjoy a lot of QS there, Sci Fi is great for apps and shakes and is very cool to see.
Epcot - Biergarten and the QS near Living with the Land are really good. Garden Grill was ok but probably wouldn't repeat. Akerhaus breakfast is very good but it's a pricey princess meal so maybe not worth it for 2 adults.
Turf Club we think is ok. We've only been there on the dining plan and we never enjoy having the plan, so that probably colored our opinion. We eat better and spend less when we just buy what we want when we want it.
We were unimpressed with the food at BOG. The inside is WOW but the food was just meh.
Beaches and Cream was the only total let down we've ever had at Disney and it was bad enough that I don't think we'll ever bother a 2nd try.
