I think this is the dive bar I've been waiting for my entire life.
I'm a punk kid and I was eagerly searching for a place where my studded/patched vest didn't make me stick out like a sore thumb in Vegas and I was waiting for the day during my entire trip that I'd get to go to Double Down. I finally got to and I was one happy camper.
The DJ was blasting Minor Threat and 7 Seconds when we walked in which was already a great start, and he came up to us and said he took requests which we quickly obliged. I downed 4 shots of Ass Juice, which is surprisingly good (a grape-tasting concoction) and it put me in the proper mood. A bunch of random strangers of literally every variety came up and congratulated the wife and I on getting married, except for the couple next to us who ran off to the bathroom to have sex. Dammit, they beat us to it.
I want to pick this place up and drop it literally everywhere I travel. There's nothing else in the world like Double Down. Loud, fast, fun. The only way to enjoy life.
