Tea shops in Boston?

I'm taking a short day trip to Boston for my birthday later this month and not having much luck finding any tea shops through google. Are there any good places to shop for loose leaf tea or a nice cafe to sit down and have a drink at? Most of the other things I have planned are around the North end of Boston and it would be preferable to stay in that area but I could make a detour for a really good find. Thank you!
