Oregon Chai is one of my favorite chai brands, and not surprisingly, other than Starbucks, this is the first chai that truly sets itself apart as something that doesn't taste like a potpourri factory exploded in my mouth. For the record, that's a bad thing. The mochas are also surprisingly decent at Einstein, and hold up to the standard Starbucks set with the Frappuccino (albeit, this is at a lower price point in my area), but the fact that the company partnered with a legit chai brand pushes this into first place. And you don't have to be an Einstein to realize that. (Sorry.)
You probably know this if you go to Panera in the summertime: its drinks are a cut above the rest. The iced caffe mocha is in the top tier of mocha drinks in the coffee-chain space. But the mango smoothie is the best cold drink, and that's something I'm not sure I would've written prior to gorging myself on iced drinks before melting on the sidewalk into a puddle of ice and coffee. This isn't a boring smoothie with mango and milk. Panera's offering includes orange juice, banana, vanilla yogurt, and ice. You can get coffee drinks anywhere, but a smoothie this good is much more difficult to find at any coffee chain.
