As Pat and Sheila noted, there's Bennigan's, Wendy's and Chick Fil A within walking distance on the same side of the street as Vistana. On the other side of the street, just before Bahama Breeze and the Golden Corral, are a Landry's Seafood and a Lone Star Steakhouse. There are several options if you continue under I-4 toward Downtown Disney - Perkins, Red Lobster, Olive Garden, TGI Friday's, Jungle Jim's, a Quiznos, McDonalds, an IHOP, and I'm sure there are a few others that I'm just not remembering. Lot's of additional options at the Downtown Disney Marketplace and Westside. On site there are a few bar and grill options and a Pizza Hut.
