Open D&D Games in the Denver Area

I went to high school in Evergreen and college in Boulder, but I've lived on the east coast since 2000. I'm back in the Denver area this month taking care of my brother, who is recovering from cancer treatment. He has expressed interest in getting back in to D&D. Are there any open games in the area that I could take him to? I saw some posts about Alamo Drafthouse. Unfortunately, that's not until next month, but we will definitely check it out.

Thanks in advance!
