Ice Barcelona is a bar completely made of ice down near the beach in Barceloneta. They have recreated famous parts of Barcelona in ice; the lizard from Parc Guell, the Sagrada Familia and many other incredible ice sculptures.
Everyone is given the same coat so as not to get cold and then you can sit, relax and drink in one of the most unexpected environments. They have an extensive list of cocktails and you can have a sub zero beer. The Ice Bar is understandably very popular so they suggest that if you are in a group bigger than five people you should book ahead and if you are more than 10 they ask you to leave a deposit.
