As of September 1 2008, the Star Trek Experience and Quarks will be no more.
Upon finding out the impending closing date was set, my wife and I went to Vegas specifically for both the ride and the bar. We had been before and always found friendly Star Trek nerds at the bar. Our bartenders and waiters were quite speedy. I never came for the food, but rather just the atmosphere and actors, all of whom were deep in character and made the entire trip as worth it for me as they could.
I will miss the ride and the Bar. Live Long and Prosper Quarks.
