The British Bulldog, Denver

The Vibe: The place may look like your typical Arsenal bar in London, but The British Bulldog is actually the unofficial headquarters of the American Outlaws, the U.S. team's extremely enthusiastic fan army. That means you might want to put on a Chris Wondolowski jersey before waving into the screaming crowd and ordering a local microbrew and some curry.

The Game to Watch: When the U.S. kicks off against Ghana on June 16, the bar will be as packed with Outlaws as a John Ford flick.
