Yes! So great!
This thread has convinced me. Our last night at WDW will be spent at MK for Wishes and MSEP and late night rides (Jungle Cruise!). We will partake in some hot dogs at Casey's on this night! And it will be marvelous! LOL!
**I don't know the hour of the Piano Player @ Casey's. If this is an important piece of your calculus, look around for those particular details.
We're known to have early dinners, or sometimes a big lunch with an understanding that at some point in the day, we're gonna' want one of our favorite food things - Magic Kingdom has both Casey's & Sleepy Hollow (for lunchtime Sweet & Spicy Chicken'n'Waffle and other savory combinations).
Casey's always seems to be where we go if we're back in the MK at night looking for a snack. One [1] hotdog/sausage is plenty for a snack (particularly the BBQ Slaw & Chili Dogs). But going to Casey's around lunchtime and listening to the piano is something special. So too are the treats at Sleepy Hollow if you're behind the stage (so-to-speak) from Cinderella's Castle when the show is being performed; I don't know if this view has been impacted since the renovations around the stage area.
The only other Park where we enjoy the food is Epcot. France gets the nod for their wine bar, fresh sandwiches next door, and ice cream in the third establishment. Tutto Gusto Wine Bar in Italy & Tequila in Mexico (never on the same day for us) round out our favorites.
50's Prime Time has excellent Maragarita's to-go while grabbing pretzels and popcorn from any vendor, otherwise, the food at HS is 'meh'. Although, both Fairfax & Minnie's have 'Foot Long Chili Cheese Dogs' (where Fairfax used to have the Casey version & a Mac'n'Cheese Dog (yes, really).
Our favorite food at Animal Kingdom is someplace else - back at ESPN Zone when we take the bus back to Boardwalk vicinity for the cold beer & nachos.
