We were in Denver last weekend, and we partially went because we thought it would be open and we'd be able to visit (remember, it was announced that it was going to open in May of this year).
We have some friends in the local area, and they said it's like getting into Fort Knox. Suffice to say, we didn't get in. Only media has had any luck so far; no dice for the general public. People have had their names on the waiting list for months, myself included, with no results. The suspicion is they're still having issues with the staff wages/no tips issue, but there isn't exactly a lot of clarity happening right now.
Fortunately I had been there before a few times, but was really curious to see how the new food stacked up. Maybe next time.
