If you want to escape from the centre of Frankfurt, or have a laid-back evening out, then head for Sachsenhausen on the south bank of the Main. Although it has been part of Frankfurt since 1318, this city-within-a-city retains a distinctive atmosphere. It's best known as the "apple wine quarter", in honour of its most famous product, which is served in practically every bar in the area, and it's here that you'll find Frankfurt's most civilized nightlife. In Schweizer Strasse there's every imaginable kind of speciality shop, while in the old Schlachthaus (slaughterhouse) on Deutschherrnufer (opposite the Flösserbrücke) there's a Flohmarkt (flea market) every Saturday morning.
