Arnulfstraße is a very long street starting at the Hauptbahnhof and ending at Romanplatz. Interesting things on this street are the BR building (Bayerische Rundfunk) and the GPO, General Post Office or Hauptpostamt. The building that houses the sorting offices is an engineering feat of achievement for the time it was built.
Also located on Arnulfstraße is the Augustinerkeller - a fantastic location all year round. In summer months you have the beer garden offering a nice mixture of sun and shade. Over the winter months you have the option of heading indoors to the keller for great food and beer.
