With its loud punk rock music and trippy decor -- vivid psychedelic murals cover every inch of the walls and its slogan “Shut Up and Drink” is painted clearly on the ceiling -- Double Down Saloon isn’t for the faint of heart. From Monday through Thursday, this dive will sell you all the “J” whiskies you want (Jack, Jim, Johnny, and more) for $5 apiece in a crazy midnight-to-2am happy hour. While you’re there, try a bacon martini, which comes garnished with a Slim Jim. Also available, Ass Juice (the bartenders won’t reveal what’s in this dive’s popular shot, which is probably for the best). Overcome the ick factor, hand over $4, and find out for yourself.
