This is solely based on the chai I ordered....
It was gross. I don't really know what else to say. I'm always hesitant to order a chai at chains because they usually use a powder based chai mix instead of the chai concentrate most independent coffee houses (and Starbucks=Tazo brand) use.
I have to preface this by saying I hardly EVER throw food or drink away if I'm not into it. I usually suck it up with a good effort. I took the first sip and realized this wasn't going to end well. It was so sugary sweet that it overpowered every taste bud in my mouth. I tasted no spicy kick a chai usually has. Sometimes if my chai is too sweet I'll add more ice cubes or milk but there was no helping this little guy out. It was a waste.
I threw it out after a couple sips. $4 down the drain, literally.
So stick to a water or pop while visiting a Panera, It's safer.
