I've always been greeted by friendly staff, never had more than two or three people in front of me in line, and my drink has always been delicious and correct. If that's not a good coffee plan, then I don't know what is. I also love their 10 cent off trivia questions they have daily, it's a nice little idea that gets your brand juices flowing.
While the raspberry campfire mocha is delicious, I think my all time Caribou favorite is their white chocolate crafted pressed (their version of cold brew). Do yourself a favor and give it a try.
