Hailing a Cab in London
In the daytime, I felt completely safe walking around most areas of London. Here I am in front of the National Gallery of London, which seemed much like the Met in New York.
At night, things tended to get more shady. The London Underground doesn’t run all night and after leaving a club, it often took around 20 minutes to find a cab. After I flagged down a cab, the driver often would not take me where I wanted to go because it was out of his zone, even if just by a few blocks. If he agreed to take me anyway, he wouldn’t run the meter. Make sure to agree on a price before getting in and don’t feel the need to tip as it’s not the norm in London.
Definitely don’t leave places alone at night. Wait for a cab with trusted guys and travel in groups.
