I found a new teashop in the Vista Ridge Mall (Lewisville). The shop goes by the name, "The Leaf Market".
Their Dragonwell- Smashing and quite possibly the best i've ever had.
Their Darjeeling - Also, very good and easily a tie with Rishi's Second Flush.
For anyone in the area, I reccomend a little visit. Their teawares are of better quality and price than other local Shops like Teavana. My cup and pot have been delightful and the owners of the shop are fun for conversation. While they are still growing and expanding their stock, they have a few Oolongs, Greens, Blacks and White teas.
Ignore the flavored stuff, it's there because it sells - the real gems are the traditional teas. Hit them up and have a cup!
