Our mother always told us to respect our elders. So we're giving mad props to the 57-year-old Don's Club Tavern, a smoky dive bar that welcomes everyone with open arms -- from the regulars who plant themselves daily on Don's bar stools to the college kids in search of a decent pool table and cheap drinks. With faded family pictures and posters of Ireland adorning the dark, wood-paneled walls, and the original cash register still ringing up drinks, you'd have to search high and low to find another bar this authentic. Sadly, owner Donald Aymami passed away earlier this year, but his wife and family have vowed to keep this Denver institution alive. And for that, we're grateful: Sixth Avenue just wouldn't be the same without the ancient neon "Mixed Drinks" sign guiding us home.
