This tea shop in proximity of the old city centre celebrates its 30th anniversary this year. Originally founded by an Englishman, this shop sells everything from different teas to marmalades, colourful cups and tea pots (some of which in fantastically odd designs), as well as little guides and booklets on the comforting world of tea.
(Note: due to recent events - and subsequently more interest in this topic - staff are more than happy to answer questions on the origins of their teas as well as on the existing supply of tea from Japan)
