There is a Macaroni Grill and Chili's in the airport.
If you got to mapquest and put in Restaurants,
One Airport Way, Orlando FL, 32827 I came up with quite a list....
If you leave airport property, you would probably be best to head toward Semoran Blvd (436N), you will find:
Tony Roma's
Bennigan's
Friday's
Chili's
Cracker Barrel
and probably many many more.... within about 5 miles or so.
