Here are some of my favorite go-tos, at a variety of price and scope levels (and not knowing fully what your taste in food and drink is,
@Cup_Of_Coffee!):
Magic Kingdom
- Sleepy Hollow Refreshments: the sweet & spicy chicken-waffle sandwich is one of my favorite options for lunch.
Epcot
- Spice Road Table (Morocco): if you're willing to try some Mediterranean small plates, this menu has a great variety, and everything I've ever had here has been quite tasty. Good cocktails, too, and beautiful lagoon views. I've never made a reservation here, but have been able to walk up and put my name in, and usually get called back within 5 minutes.
- Tutto Gusto Wine Cellar (Italy): essential if you like wine. The wine list is extensive, and the atmosphere is phenomenal. Don't know their procedure post-pandemic, but prior, you had to walk up and ask about availability.
- Hard to predict exactly what the Festival booths will have on offer, but India has had a Madras Curry dish in the past that I thought was excellent, and Spain's charcuterie cup is a good (portable) sampling of olives, cured meats, and cheeses.
- If you need to satisfy your sweet tooth, almost literally anything inside Karamell-Kuche in Germany is worth trying.
Hollywood Studios
- Ronto Roasters: an obvious and slightly boring suggestion, but I think the Ronto Wrap is a quality item! Can easily be a lunch in itself. I don't know if they're still mobile-order-only, but they were when I was last there.
- Sci-Fi Dine-In: the food is unremarkable (it's fine), but the atmosphere inside is exceptional. If you're a horror/sci-fi fan and want a table service meal in the park, it's a no-brainer. You'd need a reservation well in advance of your trip.
- Hollywood Brown Derby: generally I'd say it's quite overpriced except for the Cobb Salad... but that's a good enough item to make the Derby a place worth considering
if you really want some Old Hollywood vibes. Definitely need a reservation in advance, though.
Animal Kingdom
- Satu'li Canteen: all the customizable bowls here are great (and a pretty solid value as far as theme park food pricing goes). They've been heavily pushing mobile order here.
Disney Springs
- I know it's a chain of sorts, so not especially exciting or unique-to-Disney... but the sandwiches at Earl of Sandwich are pretty good! Especially the Holiday Turkey. Line can be slow-moving depending on what time you're there, though.
