Myself, my brother (40) and two children, girls, 2 & 5 ate at Jungle Jim's in mid-November.
We were extremely pleased with the menu and the service. I was very tired of the "usual" parkfare and Perkins, McDonald's, etc. We were pleasantly surprised! I was feeling SO TIRED of burgers & fries, that I had a real oddity from the menu! It was a huge and soft croissant sandwich with cream cheese, smoked turkey and cranberry sauce...sound weird?! I thought so too, but I looooved it! Try it if yer feeling froggy. My kids also liked it here, as they had a cute animal-ish menu and a big elephant or some animal in the front to climb on, and little cups and swizzle sticks with animals, etc.
All in all, it was a welcome change from the crowds of the chains, and I would definitely go back again...we stayed in Downtown Disney and it was a skip & jump - that's how we ended up there...hope this helps! have fun~
