Their food is a little pricey, but their tea prices are right on par, and their selection is pretty much out of this world. Moreover, their staff actually knows their stuff, so if you have a tea question, they can answer it for you instead of just making stuff up.
Sometimes it takes a bit longer than it should (no tea I know of takes more than 10 minutes to brew), but it's worth the wait. You can get them made hot or cold, with milk (or soy!) or without. Add to that a nice sandwich or cupcake, and you have a perfect afternoon snack/luncheon.
Their chai selection is wonderful, as are some of their black and herbals. If only I had the time to try everything!
