As a few have stated, there are quite a few options on State Route 535 (Apopka-Vineland Rd.). If you head toward Downtown Disney, pass all the Downtown Disney resorts, etc., the road you're on will end at 535. If you make a right, there are a number of options on the right side of the road....Chic-Fil-A, Wendy's. On the other side of the road, there's a McDonalds, Subway and a number of chain sit-down restaurants that aren't too pricey - Olive Garden, Bahama Breeze, Longhorn Steakhouse, Buffalo Wild Wings, Chevy's Fresh Mex, TGI Fridays, Fuddruckers, Pizzeria Uno Chicago Grill and I'm sure many more that I'm forgetting. Most of the restaurants that I said were on the opposite side of 535 are actually directly across the from the light at Hotel Plaza Rd. (the street DTD and DTD hotels are on) and 535.
Use Google Maps for the intersection State Route 535 and Hotel Plaza Blvd, Lake Buena Vista, FL and zoom in... you'll see exactly where many of these places are located.
