Nice environment, good taste! I have already booked it through Klook. It's super convenient. I made a reservation at 11pm the night before. I just made an appointment the next day and walked in and gave my name. The cheaper one is already the most advanced option. If you will go to Asakusa/Skytree that day, it's recommended! However, because it is located between Asakusa and Skytree, it is recommended to walk through Asakusa first, walk 10 minutes to the restaurant to eat, and then walk 15 minutes to Skytree!
