Costa Coffee

Skip starbucks. This is a great Costa.
The coffee is HUGE, and the staff is great at their job. When you step off the plane, go here.
Also has working power outlets

This costa coffee location is quite good for an airport. It is conveniently located outside of the secured area in between the departures entrance and the bus station.
With a moderate amount of seats, (probably around 30) you may or may not find a spot depending on the hour. Nevertheless it is in a wide hallway where you could find a seat in some corner to enjoy a break between your travels.
Prices are the same as any other branch, therefore you do not feel the airport is taking your money :)
Assortment is similar to other locations. Good coffee, teas, pastries and sandwiches. Special mention to their cheese sandwich after is warmed up and the inside is deliciously melt.
Service is friendly and spoke Czech, English and French. Winner!
