I’ve eaten at a restaurant in Tokyo that my friend referred to as a “tofu restaurant“. It only served dishes that included tofu in some form. The first dish was a wooden box on a hotplate that the waiter poured a form of soymilk into. It turned into a soft warm tofu paste we could eat about 20 min later. The final dish was a type of cheese cake that was amazing. This was a long time ago and I am (obviously) not an expert on tofu, but it was a very memorable meal.
