Is there no end to this mass dive-ocide in Denver? Don's Mixed Drinks [2] (or Don's Club Tavern, technically, but no one has ever actually called it that) is signing off, [3] following in the quickly fading footsteps of the 15th St. Tavern. [4] If either of these classic dive bars have been close to your heart, hurry on down for one last beer-and-a-shot or a final round of pool while you still can.
