Miro Tea's high point is actually their menu of crepes, which is saying something, because they have an extensive list of high-quality tea, and it's prepared well.
I have been to Everything Tea several times while visiting a friend who lives in Snohomish, and if I recall correctly, they are basically a retail shop (though they will brew samples). That's the only reason I gave the food and artistry low marks -- I don't recall either being present! Their tea selection is very broad and the quality is very high. They also have lots of teaware, with a focus on European ceramics.
Remedy always feels a little like being in an Apple commercial -- very clean, modern aesthetic. However, it's an awesome place to go with friends and just hang out and chat. Their snacks vary, but are always tasty.
I love coming to the Tea Cup -- in the summer because I can get a giant glass of Thai iced tea, but all the time because of the relaxed atmosphere, intriguing teaware, and wide selection of teas.
