Face it, when you travel and especially at an international airport, the place knows that it has a…read morecaptive audience so can pretty much rip you off for a bottle of water or a sandwich. Java Coffee could do that too, but since the Starbucks has already cornered that market at the Brussels airport, they only go for affordable coffee and such.
A normal fresh coffee is only 2.85 (Euro) and a larger one 40 cents more. A cappuccino, medium, is 3.75 while the large one is 3.95. They have different teas too, which are 3 euro each. You can even get a smoothie for under a fiver! If you're hungry you can get a chocolate or blueberry muffin for 3.30 and even a croissant for 1.90.
Java is located on the arrivals floor, so grab a drink before you head through security on the other floor.
