After lunch, I guided them to STARBUCKS RESERVE(R) ROASTERY.
They said that visiting this place was one of the purposes of their visit to Japan. Unfortunately, when we went there during daytime, it was very crowded, and we could not enter the store.
They visited again at night without a guide and stayed there for two hours.
The next day, they told me that last night was very satisfying and they were able to achieve one goal of their visit to Japan this time.
