Look at the menus and see what appeals. There are some new offerings since I’ve last been 11/19. I agree you should try the skewers
(Bengal BBQ) despite them being smaller and not quite as good as a decade ago. But I’ve never had a Montecristo or corn dog in decades of visiting.

We have overall not been impressed with any of the food at Plaza Inn it’s surely not going to be the best fried chicken ever.
I’ll list some of my faves but none of them may be a must do for you. Taste is subjective!
French Market-we have been satisfied every trip. I get Caesar salad. DH gets whatever and has always been happy.
Boardwalk Pizza & Pasta I love the Caesar salad and spaghetti. My sibs love the other pasta. My kids get gf pizza.
Not a must do for us every trip but we enjoy
Jolly Holiday. I get the grilled cheese and tomato soup. DH varies. He had a pretty bad holiday sandwich offering one year. Turkey and something. Who knows if they’ll ever bring it back.
If you want Mexican avoid

Cocina Cucamonga. I’ve tried many times and it’s just horrible.
Rancho del Zocalo is no longer on my must do list but it’s a viable option.
I hit up
Cozy Cone twice for their chili every visit.

I don’t like the cone and get it in a cup and ask for no nacho cheese.
I’m going to try the aforementioned Monte Cristo at Smokejumpers Grill. This place has never been a fave but it’s not horrible. I just couldn’t order an unknown at
Blue Bayou with so many other preferences. BB isn’t a must do, especially in just a 2 day trip but the ambiance can’t be beat. I don’t care for Cafe Orleans or Carnation Cafe; we haven’t had good experiences there and with so many good options in the park I don’t have time to try a mediocre sit down place twice.
Award Wieners used to be a must do. But I haven’t heard good things with their current limited menu.
Adorable snowman is on our to do list. But jack Jack’s wasn’t amazing.
