London travel tips
There are two types of bus stops in London: regular and on-demand, so the bus may not stop
Every bus route in London has regular stops and on-demand stops, so buses do not always stop. To get on the bus for sure, it is better to stretch out your hand when it’s approaching. If you need to get off at the next stop, press the stop button on the handrail well in advance.
Experience London's cultural life at Leicester Square
In the West End of London, Leicester Square is a pedestrian area where the capital's cultural and theatrical life is in full swing. 6 cinemas and more than 50 theatres offer guests a rich program. Festivals are often held in the square. In the 19th century, a monument to William Shakespeare was erected here. The area is also famous for its restaurants, pubs, and nightclubs.
Join the five-o-clock tea ceremony in London
Even though this tradition gradually becomes obsolete, you can drink tea in the restaurant of any department store or in a hotel where you will be welcome, even if you are not its guest. The British drink tea with milk, muffins or cookies, buns with cream or jam, and fruits are served with it. But keep in mind that tea drinking is not a matter of five minutes but a whole ritual.
