The burger definitely came from Hamburg. It was there that the sandwich was "modernized", using a fried cutlet instead of a piece of meat, and a cut bun instead of two pieces of bread. Hamburger is a relatively young dish. The modern concept of a hamburger developed in America at the beginning of the last century, where many immigrants from Germany and Hamburg appeared. This place is open until late and is popular for its beer and hamburgers! Bon Appetit! Translated with Google Translate
