Is the sports bar on your block owned by an old Russian dude? No matter; on St. Patrick’s Day, every watering hole is an Irish pub. It doesn’t take much to bring in the crowds: a couple shamrock signs and some specials on Guinness will do the trick.

How do you know you're in a real Irish pub? The bartender looks pissed, and you don't get light-up shamrock earrings with your third pint.
