Lots of things to do, and the people are super nice.
Another thing that's fun is to go to Fort Worth, and shop the streets there, fun little quaint shops, and they drive the cattle down the street daily. You can pet a real honest to goodness Long Horn.
There are several really neat statues that are large throughtout Dallas, one downtown, another in Las Colinas, check them out they are really quite impressive.
Deep Ellum is the counterculture area, and it's been some time since I have been down there, but can be a lot of fun.
Restraunts - Any small family owned Mexican place will do. If you are leary of that Don Pablos is a chain that has excellent Fajitas and Margaritas. Bar B Que is the other thing they do well in Dallas, ask around where the place to get the best is when you get there.
