Goodness, it has been a loooong time since I went to Teavana. After my usual tea guy, John, left all of the old employees became quite b*tchy, thus is why I left, however after starting to go Teavana again recently, the staffs has totally gotten better (if you're reading this, John, then I have to say thanks for coming back!) Well back to the main point.
Teavana barista are super friendly and are good at what they do (which can be persuasion or making a cup of tea, or five in my case). I don't know about the rest of the yelpers but I think their tea are quite affordable. But hey, that's just my opinion.
