Fox Sports on Legacy in Legacy Park off the Tollway has great food, good service, and is a great place to grab a drink. It's low light and has many monitors you can look at if your date gets boring. Plus the waitresses are HAWT.
If it's early in the afternoon, you can take her to Martini Park, but come 9 pm Martini Park gets pretty crowded. There's also a Starbucks in that same shopping center where they have live music on the weekends. Just pretty much anywhere in Legacy Park... you can't go wrong.
