I was there for breakfast but since it was late we decided to have lunch. The food was really good, we had salmon and some pasta. It was really hot. They have no A/C. Other than that, everything was fine
It is not easy to find a reasonable eatery in Frankfurt. For those whom really enjoys eating, this place is like a 'Oasis' in the middle of Frankfurt desert. Highly recommended. Go and enjoy your breakfast whole day long.
