Dallas Nightclub has been around for ages! It's on Burnet Road, between 2222 and Anderson Lane.
On Fridays, it's country night (although their website says they play some Top 40 also) and they have a free two-step class from 6:00-7:00. We'll dance after that!
Don't worry if you think you've got two left feet, just come and have a good time!
Here's their website: http://www.danceatdallas.com/index.html
