Gaylord Palms is a bit odd - kind of in the middle of nowhere, but close to quite a few places at the same time. Sounds strange, I know, but you'll understand what I mean once you've visited! Fundamentally, nothing is within walking distance, but there's quite a bit within short driving distance.
You're right on the edge of WDW property - just travel west along Osceola Parkway. As iloveokw says, travel south a short distance on South International Drive and you hit US192. Just take your pick! Travelling north on I-Drive (albeit quite a bit further - 15/20 minutes?) you will also find a huge selection. Have you been to Orlando before? What kind of food do you enjoy?
