We were just in Orlando this week staying on I-Drive. We ate at both the Olive Garden and Don Pablo's. Service was fine, the food was good, and most importantly, they were conveniently located for us (we stayed at the Embassy Suites right next door to the Olive Garden).
FWIW, whenever we're down that way, we try to go to Don Pablo's as we used to have one locally but they closed. At the Don Pablo's on I-Drive, we have found it to be consistent in service and food.
