The main hall isn't just a waiting hall, but also a market place where most things can be bought. From fresh fruit sellers to super market, postal office, banks, currency exchanges, hamburgers, coffee shops, restaurants and pubs etc. There are also travel center for information and manual sale of tickets and two large toilet sections which are under manual supervision and clean. Shower rooms are also available for a smaller fee.
The current station building opened in 1911 and is the work of architect Heinrich Wenck. The station has 7 platforms and 13 tracks. On the station concourse there are many small shops, cafeterias, and fast food outlets. All public transport within Greater Copenhagen are divided into close to 100 ticket fare zones. The Central station is located in fare zone 1, which together with zones 2 and 3 constitute Copenhagen municipality and the "exclave" of Frederiksberg municipality. As the cheapest single ticket always is valid in two zones, a single ticket bought at the station is valid within the entire city centre and its inner boroughs. A ticket to Copenhagen Airport Kastrup, however, demands the payment for three zones since it is located in zone 4 [Wikipedia.org]
