Meals and services are good. But super busy during lunch time so highly recommend to make a reservation.

Uhmmm... I went for lunch and had tan tan men. At the reception I was asked several times whether i waa sure to get in because last order was one hour later! Tant tan men taste was just ok. My partner wanted to have a menu course but no go. Either we both go course or both go a la carte. Dessert was sold out, I guess they only prepared the small sizes for a la carte menu. Course tables were properly set and prepared with towel etc. A la carte tables were bare and essential. My impression is that this restaurant is popular with a steady flow of customers so no need to break a sweat. Noted!

Their tantanmen is great. Creamy, not that spicy. Tantanmen is 1080 yen, with extra 50 yen you can get delicious anin tofu. Lunch is always crowded. Lots of people coming with group. Feels a bit weird coming here alone. Would love to try their other dishes as well in the future. Service is a bit slow.

Perfect Japanese dandan mien, and mapo tofu
