Green Tea Restaurant 1899 Ochanomizu is a restaurant/cafe which specialises in green tea and has a green tea theme. Periodically they hold classes on green tea and they invite instructors to give us fun lectures on the history, nutrition, science, producers, agriculture and different methods of making tea as well as a tea tasting experience. We also get to do the actual experiment. At the end of the class, we make our own tea and they serve delicious sweets. You get to meet with other green tea lovers and network with them. When you leave the restaurant, they give you a nice surveyor. We got a package of special green tea that only the Emperor was allowed to drink and it contained a real gold leaf inside.
