I guess that would depend on what you like to do. The Dallas Farmer's Market is a cool place to visit, likewise the Arboretum, the World Aquarium, the art museum, etc. There are fishing places at Lake Ray Hubbard or Lake Lavon. There's the Texas Motor Speedway, Cowboy stadium, hockey and basketball at the AA center, local gun shows and more.
As far as clubs, restaurants, bars, etc, I'm the wrong guy to ask as I don't drink, I can't dance if my life depended on it, and as a former classically trained chef, I don't go to too many restaurants.
