Founded in 1902, when a significant proportion of Milwaukee’s population was made up of German immigrants, Mader’s still serves classic German dishes to this day. Stars from Britney Spears and Iron Maiden, to Frank Sinatra and Audrey Hepburn, have dined here, and it's seen its fair share of presidents, too, including JFK, Gerald Ford, and Ronald Reagan. Fans recommend the Kennedy-inspired German Sampler, which includes a wiener schnitzel, kassler rippchen (smoked pork chop), and sauerbraten (marinated roast beef).
