If you are going on 417 (the Greenway)... let's see I used to live at these exits (8 years ago!) and there are tons of new places....
Exit at Orange Blossom Trail, or next one, John Young Parkway (maybe 15 minutes from airport?). There is a Ruby Tuesday's, Donato's pizza, I think a Steak n Shake maybe?? And tons of new stuff... I swear every time we go back there are so many new places popping up. I can't think of what else, but lots.
Also if you get closer to Disney you could go to the Crossroads plaza across from DTD, there are lots of restaurants there too.
Maybe someone else knows where I'm talking about and can think of more restaurants there??
