What to See: Had a Budweiser lately? You can thank the Czech. Pilsner, a type of pale lager, was invented in the town of Pilsen, near Prague. Try a freshly brewed cold one at the Pilsner Urquell Brewery, one of the few places you can sample a cask-conditioned, non-pasteurized beer similar to what 19th-century drinkers tasted. If you want to taste more than the Czechs' most famous export, visit during Prague's 17-day Czech Beer Festival for traditional fare, live music, and costumed servers pouring more than 70 brands of domestic beer.
