Nothing! this is the armpit of Texas...
but there is Southfork Ranch, a fair bit of nightlife in the West End, the aquarium (which lost its accreditation a few years ago), the museums at Fair Park, the 6th floor museum and the site where JFK was shot (he was about to spend all day in Dallas - they really did the guy a favor), some wineries in Grapevine, cowboy type stuff in Fort Worth and the movie studios in Irving. People are nice in Dallas and restaurants diverse and plentiful.
