I'm about to head down to Shotgun Willie's, the titty bar about a block from the hotel.
I've actually been there.
A few years ago, I went to Denver for a weekend, when the Cardinals had a weekend series against the Rockies. Stayed, if not in your same hotel, one near by it, as I remember going to Shotgun Willie's.
The area around Coors Field is called LoDo, or Lower Downtown. Pretty much all the bars around LoDo were fun, I think we ended up at one of those dueling piano bars.
