What can you say about the Milestone? It's a classic, it's history, it's one of the most underrated gems Charlotte doesn't seem to exploit.
You don't go to The Milestone to look pretty, sit & relax to strike a casual conversation or for the good beer. You go to The Milestone because it is The Milestone and you're gonna get an experience. Good/bad? you decide but it will definitely be an experience.
Walls are covered with historical and new graffiti and stickers which is great to gawk at. I wish they'd work on their sound though... pretty horrible, but given that I only go to see punk/metal/hardcore shows it doesn't make that big of a difference.
