Barcelona travel tips
The restaurants near Barcelona’s beaches offer lower prices during the day
In Barcelona, the restaurants near the sea are quite expensive. Nonetheless, during the day, you can have a good dish for €9-13. Note that if you decide to go there in the evening, the prices will double!
Barcelona supermarkets don’t sell alcohol after 23:00
Note that street sellers may work even later, but they usually offer overpriced, low-quality drinks. In some neighbourhoods (Raval, for instance), owners of minimarkets don’t trade alcohol for religious reasons. Start stockpiling all the necessities for a relaxing evening in advance!
Come to see the Torre Agbar skyscraper at night in Barcelona
The Torre Agbar, erected in 2005, has become an important element in Barcelona’s urban landscape. The bullet-shaped skyscraper is 145 metres tall, making it one of the highest structures in the city. This juggernaut looks impressive in daylight. However, it is even more stunning after the sunset, when over 4,500 lights illuminate the whole building. Don’t miss this sight!
