I have a seven hour layover at Brussels airport, and I'd like to know whether there is enough time to leave the airport and go into the Brussels city center for a beer or a meal?
If so, what transportation is available, how does it work, how long does it take, and how much does it cost? Are there convenient luggage lockers in the airport so that I can avoid taking my carry-on luggage into the city?
This layover is from 8:30 in the morning to 15:30 in the afternoon on a Monday, and the flight is arriving from the United States. The outgoing flight is within Western Europe.
