I walked by Dado Tea on Mass Ave. between Harvard and Central Squares this evening and spoke with the owners who were working inside. They're planning on opening on the 27th, next Friday, and will be offering free coffee and tea all day. The menu is pan-asian, serving a wide range of drinks as well as some prepared snacks, both asian and western. The tea comes from the same Taiwanese supplier that supplies Ten Ren in NY.
Tea-related accessories, produced by local artists, will be sold. I peeked in, and they have a beautiful selection of ceramic pots and cups.
The owner, who's a Korean gentlman, also mentioned that Koreana on Prospect Street(near Central Square) will be reopening shortly as an upscale Korean restaurant.
