Besides the national chains around here, I'd recommend the following: Orlando Ale House, Sam Sneads Tavern, Tijuana Flats (fast Mex), and Cheesecake Factory. If your budget can handle it then try Season's 52 or Del Fresco's (they're not cheap). There's a ton of more resteraunts and stores on International Blvd. If you're looking for more of a night life, then hit the Blue Martini or Church St/Orange Ave in downtown Orlando.
You also have the parks (Disney, Universal, Sea World, Wet n Wild, Islands of Adventure, Cypress Gardens, Silver Springs). Daytona Beach and Cocoa Beach are less then an hour away. If you're a NASCAR fan, then Daytona USA at the Daytona Intl Speedway would be a good place to visit.
