Very nice!
A very relaxing experience here! The people are very nice too. They aren't going to walk you through everything, at least not by default. Maybe if you engage them earlier they might give you recommendations, otherwise read through the extensive menu. I spent about an hour and a half here, had a great time too. The tea we selected was pretty good, not awesome, but decent none-the-less!
A large selection of tea, lots of background on it as well, but no "special" or real "premium quality" stuff it seemed.
