Sen is a Japanese restaurant in Gojo, Kyoto, serving kaiseki that features seasonal ingredients. The courses include premium ingredients such as matsutake mushrooms, matsubagani crab, and black abalone, along with fish dishes, and finish with a choice of kamameshi, grilled mackerel sushi, or Japanese-style ramen. It operates by reservation only, with an 8 to 10 seat counter facing the chef where the same course starts at once for everyone. The course lasts more than two and a half hours, which can make the schedule tight.
