London travel tips
Ride a river tram on the Thames in London
River trams are more of a tourist mode of transport than a public one. Boats run along the Thames from Westminster to Greenwich, stopping on the north and south banks. You can choose from several companies that offer river cruises, such as Thames Clippers or Thames River Services.
Visit St Paul's Cathedral, which is visible from any part of London
Today, the cathedral is the seat of the Bishop of London. Built according to the canons of the Protestant Church, the cathedral is simple and well-thought-out in proportions. Its decorations are amazing stone carvings and stained glass windows. The service is accompanied by one of the oldest and finest organs in England. Admission is free only during Sunday services. A regular ticket costs from 17 pounds (20 euro). Shooting is prohibited.
Taste strong alcohol in London, preferred by British themselves
The most popular alcoholic drinks among Londoners are beer, gin, and ale. However, apple wine goes almost on a par with them — cider, rum, and Pimm's (fruit alcohol). The latter is served as a cocktail of cucumbers, fruits, and alcohol — an unusual drink that surprises tourists.
