I like Jerusulem Restaurant which is in a shopping center off 535 near the intersection of 192. If you like Greek style food it's similar, check it out. There is a coupon offer on restuarant.com for them which I've used for take out orders coming from the parks & back to my unit. I've also been to King O Falafel which was good too, off 192 in Kissimmee heading west; it's casual counter service with tables that used to be a sandwich restaurant so pretty much the same set up with really good food at good prices. There is El Tenampa for Mexican food also off 192 heading east.
I've never been, but I know there is a Sweet Tomatoes in Lake Buena Vista which has coupon offers almost always & it's got good reviews for having fresh food at a good price. Another place I've heard good things but haven't been yet is Sushiology in Lake Buena Vista (not sure how many tables inside if any or just for take out).
