When I moved here a few months ago I was sorry to see that this chain of upscale tea shops had not made it to Arizona. So, I was thrilled to see that one opened up in the Biltmore Plaza across from my office building.
Teavana is a unique little store that sells, literally, hundreds and teas and blends as well as tea accessories. The staff is familiar with the product and can brew just about anything on premises, so you can try before you buy. The teas are high quality and there is something here for everyone.
Also, they have great prepackaged gifts. I have given and gotten gifts from here and love it. I def. recommend the one cup tea maker they use in the store - it is an easy way to make one or two cups of loose tea at home without any mess and it is not terribly expensive. A good alternative for your caffeine fix.
