The staff at this Caribou Coffee are always quick, friendly, and polite. I've gone through the drive through several times and they have never slowed me down or bungled my order. I also went in with a woman I PCA for that lives nearby and they were really kind to her and chatted with us while we waited for our drinks. I was really impressed by the patience of the baristas when we stopped in.
I suppose I should mention that I gave 4 stars only because I never buy their coolers anymore. This is due to a certain barista at the Lake Street Lund's Caribou Coffee, who imparted the knowledge upon me that they use 'powder mixes' in them. Yuck.
