Before, I didn't know if I needed a reservation and just waited in line on-site. But this trip was short, so I made a reservation and used it. Soon after, I ordered and paid (when paying, you need to decide what you want to eat/buy!). Then, I was immediately guided to my seat and enjoyed ramen with the cute Chiikawa, Hachiware, and Usagi characters. It was so delightful. I highly recommend it to anyone who loves the Chiikawa characters! If you order a drink, you also get a random card, which is fun! I personally found the ramen delicious, and all the drinks were tasty too. It was so great that I want to visit again next time.
