Hi Dive Lounge is kind of like a hobo in a tuxedo. As the name suggests, the West 39th Street joint is a classy place (the food doesn't resemble bar fare in style or price) that serves cans of bottom-shelf beer from a creaky old vending machine. But do you really want to be the person ordering Hamm's or High Life in a place that serves polenta and $8-a-pint microbrews? At Hi Dive, yes, you do. If the heat isn't too sweltering, the rollback windows are open. The Royals are on the TVs, and customers are being generous with the jukebox. Neighbors wander by pushing strollers or walking dogs. Nobody cares if you're drinking piss water. It's a live-and-let-live joint. The beer is cheap, but it's the rich life.
