When we arrived, there were huge queues for both tea houses, but the wait ended up being quite short, only 15 minutes, being on a Saturday at around 4pm.
They only have one thing on the menu, so they serve you directly the tea, and then bring you the mochis. The tea tasted great and was of good quality, and I absolutely loved the mochis, and would love to have the opportunity to go back and eat them again! I found that the sauce was really special and not something you can eat in other places. Really worth a visit! Also, they are better eaten hot, once they cool down the flavour is not that strong anymore, so I would recommend eating in and not take out!
