I'd say do Casey's corner if they are first timers, its not a sit down meal but an MK staple!
sit downs at magic are nothing amazing as there so much more things to get excited about in the park.
i'd go to the poly. do some O'Hanas (breakfast or dinner! or both lol)
lol made me laugh this.
i like vloggers, they don't offend me, give me info and insights into the parks when i cant get to the parks. (i live in the UK)
i tend to go yearly for 2 weeks for the past 10 years, i have only seen 1 vlogger, we were in the background in a restaurant, searched youtube...
AK - Flame Tree, those Loaded fries though :)
MK - Casey's, just for nostalgia if nothing else, Hotdog or corn dog bites are tasty
Epcot - La Cantina de San Angel - nachos are a great sharer and fill you up.
HS - gotta be a turkey leg :)
we always love narcossees and i don't hear many people talk about it. so i'll say that is my under rated choice.
my over-rated choice would have to be Be our guest - its a fun and well themed restaurant but the food is pretty meh for the price range. However, we liked it enough firs time round...
