About Frankfurt
City overview
Frankfurt is a Main River finance city with a compact rebuilt old town, a serious museum bank, and skyscrapers that make the skyline feel unlike any other German city. The traveler frame is Römerberg and Altstadt for history, Sachsenhausen and Museumsufer for riverfront culture, and Bahnhofsviertel and Westend for the dense urban edge around the Hauptbahnhof.
Food & drink
Frankfurt food is tavern and market-focused: Frankfurter Wuerstchen are slender smoked sausages, gruene Sosse mixes herbs into a cold sauce for eggs and potatoes, Handkaese mit Musik marinates sour-milk cheese with onions, and Apfelwein is poured from blue-grey Bembel jugs. Kleinmarkthalle, Fressgass, Dauth-Schneider, Lorsbacher Thal, and Textorstrasse taverns add schnitzel, Bethmaennchen, and cider-house meals.
