Located in West Germany, Schöneberg has long been an area of progressive ideas, broad avenues, and plenty of choice in the nightlife and cuisine department. The lively heart of the LGBT bar scene beats from Fuggerstrasse to Gleditschstrasse, joining a conglomerate of beer-serving cafes and traditional schnitzel kitchens, making for plenty of good times no matter your persuasion.
A great place to orient yourself would be Winterfeldtplatz, where produce stalls can just be the start of a weekend that could include Middle Eastern food (Habibi), highly recommended cocktails (Green Door and Stagger Lee), and an assortment of sidewalk cafes both to the north and south. Although clubbing isn't priority number one in Schöneberg, it'll be hard to fight the appeal of mega-club Goya (Nollendorfplatz) or Latin favorite Havanna (Hauptstrasse). Other area favorites include Berlin Homemade Ice Cream on the west side of Kleistpark, the upscale ambience and lengthy wine list of More on Motzstrasse, and the German grub at Renger-Patzsch on Merseburgerstrasse.
Despite its proximity to the center of Berlin, Schöneberg is one of the more off-the-beaten-path neighborhoods around because it doesn't have many of the tourist staples like the neighboring Tiergarten (worthwhile for green space, museums, and beer outlets) or Charlottenburg (the palace is incredible). This is good! If you want an authentic area to mix with the locals and still be within a bike or taxi ride of the tourist traps, then hang out in Schöneberg.
