Dallas/Irving covers a wide area, and I am not sure how far you are willing to drive.
I am not into clubs, either. Here's a few suggestions off the top of my list:
1) The Angelica (Angelika, maybe) theatre. This is a really neat movie theater that shows a LOT of independent and hard to find films. You can also order food and alcoholic beverages to take in the theater. It makes for a really nice, different evening.
2) Stonebriar Centre in Frisco. Yes, it really is just another mall, but it is probably the nicest one in the area, with a lot of cool stores. It is definitely a way to spend an evening.
3) Dallas has a pretty lively theatre scene. I am not sure when you are going to be here, but Dallas Summer Musicals has a lot going on this summer, and there are NUMEROUS plays in smaller theatres around the area. You could just google Dallas theatre and come up with a LOT to do.
4) The Texas Rangers play not too far from there (about a 30 minute drive). You could go to Arlington and catch a game. There is a REALLY good "hole in the wall" pizza place on Fielder and Randol Mill in Arlington called, "Mama's Pizza". It's a dive, but the pizza is truly incredible!!!
5) In Grapevine, there is an outlet mall (Grapevine Mills) that is HUGE. It is definitely a great way to kill an evening. They also have an AMC theatre that either has 24 or 30 screens....I do not remember which.
6) If you are here on a weekend, there is Trader Joe's Market in Grand Prarie. It is an open-air flea market that sells everything imaginable, and then some.
7) If you want REALLY good Tex-Mex, trek over to Lewisville and go eat at Angelina's. Again....a hole in the wall, but super good, authentic Tex-Mex.
If I can think of anything else, I will be sure to let you know!!!!
