I love Cartel coffee and the fact that they have an airport location is fantastic for those early morning flights. The best thing about this location is that even being a high traffic airport location they still put the same care and quality into every order just like at the standalone locations.
The staff is always friendly and helpful especially when trying to decide which drink to go with. The real impressive thing for this staff is that they can turn out the drinks quickly and with quality even when there is a line. Speaking of the line it's usually less than sub-par overpriced chain location just down the terminal.
If you need a wake up while at the airport be sure to come over to this location by gate C14. It's worth the walk if you are in the C gate area (or are on a long wait in the other gates).
