It's 25 years since the Berlin wall was demolished, since then Germany's capital has seen an explosion of international visitors. A place where tourism is growing twice as fast as the German average.
From dawn till dusk and back, the city has a growing 24-hour reputation which fuels a constant economy.
It's down, in large part to the Berlin's 24-hour public transport system, a limited service during the week, and a full service which operates over the weekend.
Paul Tighe is a Dubliner who works in a well known Berlin bar. He has experienced life in London, but safe to say - he prefers Berlin.
In the bars and clubs the atmosphere is different, the pressure is obviously off. Wherever you fancy going, whatever the time is, you can get there quickly and cheaply.
For the tenth year in a row tourism figures in Berlin are expected to break records.
It's anticipated that 30 million people will visit Germany's capital this year.
The 24 hour weekend transport service has played it's part, the night time economy has doubled since it was introduced.
It's true to say that the impact is not all positive, some areas of the city have seen levels of crime rise since the 24 hour system was introduced - namely drug dealers and pickpockets.
There have also been complaints from residents about an increase in litter and noise. Like Berlin, London will have to adapt - and it has much to learn from its German counterpart.
