We went there several times. It was a blast!
The Warp Core breach is the greatest drink ever.
We had a Klingon in Quark's, and a guy was sitting at the bar and ordered a white wine. Oh, man! The Klingon was relentless! "Did your mother give you permission to drink, little man?" "Would you like some finger sandwiches with that?" etc. It was hilarious.
The last time we went we did the backstage tour. That was awesome.
I wish it was still around, as we go to Las Vegas frequently.
