There's a magnificent, jaw-dropping Gothic cathedral that everyone comes to see, and a museum bursting with Warhol, Lichtenstein, Oldenberg, Wesselmann, and all the Pop Art you can handle. There's rich, creamy German chocolate, the best that money can buy, and locally-brewed Kölsch beer served in small, 6-ounce glasses. And there's a "party mile" where you can drink and bar-hop till kingdom come; and the Karneval, the biggest street bash in Germany, where you can literally let your hair down and get wicked drunk! "Wundervoll! Nicht wahr?"
