The dance bar, Rockin' Bar D, remains. As far as I can tell, they didn't make any major changes to it. The Dueling Pianos bar, Off Beat, has become Diversions, a neighborhood pub/sports bar.
The ESPN Sky Box is gone, it is now a teen club called "The Stack." The former teen club, Common Grounds, is now an adult coffee bar. The name escapes me right now, but I think it's called The Cove Café (as in Quiet Cove). I am probably mistaken about that.
I think that's the extent of the changes. There would seem to still be plenty to do at night. I will find out for myself shortly.
