This has to be the most famous cantina in the world. It's the most infamous in Mexico, and where else to they have infamous cantinas? Started by Russian settlers over a century ago (almost everything in the Baja was started by somebody from some weird place for some nutty reason), Hussongs has evolved from a Western hole right out of the movies into an international bawdyhouse where Lee Marvin and John Wayne cavorted, into THE place to toss back a tequila in the Baja--with an incredible T-shirt and bumpersticker empire that was plastering its strange name all over the Americas when the Hard Rock wasn't even a gleam in some marketing sociopath's eye.
Like Disneyland, the reality of Hussongs isn't quite up to its reputation--but what the hell do you want from a Cantina? Its an old place you go in and drink. They even allow women these days. Mostly you can say you were there. If they don't believe you, show them your T-shirt and bumpersticker.
Seriously, Hussongs is a place you ought to hit. You never know what the scene will be. It might be a bunch of college knuckleheads, or it might be full of bikers on a run, or it might be the usual Baja crowd. But it's worth stopping by at the North end of the main drag (Lopez Mateos) and Calle Ruiz.
