I was originally going to post I disagree because think ak and mk both have great quick service IMO but I think you may be right that hs has argument to edge them out.
Ak is probably my favorite with satuli, flame tree, and harambe. Mk sometimes doesn’t seem great but I do enjoy sleepy hollow, Casey’s, pecos Bill, and Columbia harbor house (can even add be our guest more for atmosphere if we assume menu goes back).
HS I’ve explored less but greatly enjoyed woodys lunchbox and rontos. Also hearing good things about docking bay 7 and while not a quick service per say ogas canteen has to count for something. I guess we are cursed with having so many great options these days haha.
