I go to this place at least once a month (I live across the road), which is about 1 meter from the…read morefront door. Unfortunately, Leuven is not blessed with an array of food, as its more general attention is drawn to the beer scene.
So, let me say that I've been to this place at least 30x and I've probably eaten every item of sashimi, nigiri, and half of the rolls. I still go back. It's cheap. And you can drink Stella for 2 euros while you fill your gullet with fresh fish for 5. No kidding. The à la carte is cheap. They can be really busy some weekends, so reserve a place, or prepare to wait. Oh and the people are super nice, despite the busy scene.
