I love this place.
Have been here couple of times and have to review this here now.
Please note: reservation is a must. The place was sold out every time I've been there.
Very friendly welcoming personnel.
The menu is limited, but you have to go for the typical Regional dishes (Sushi & Sashimi can be eaten anywhere)
Aal auf Ruehrei.
Or you go with the Hamburg-Menu @ 49 Euro
