A must-eat restaurant in Frankfurt, all locals go there, basically no tourists, and it was recommended by a friend who lives in Germany all year round. It is in the city center, and it is difficult to park. It is best to take a taxi or bus. The restaurant is open-air. We went there in December and the roof was covered and the heater was on. It is said that it is very comfortable to drink and eat meat in the open air in summer; there is an old tree in the middle of the restaurant, which has a history of many years and has a special atmosphere... There are so many people going there, and you have to queue up or share a table with others if you are late. The locals are very warm and polite.
