Maremagnum

The Maremagnum Shopping center (which has not only fans amongst the inhabitants of Barcelona) is a big American style shopping mall. Some like it, some don't. I liked the Aquarium next to it, although this is expensive it is worth the trip.

You can find there not only the best shops in Barcelona, also good pubs and curious events... but, the best is the sight that you can have from there: the port, the people... authentic barcelonian people. Good point: Only mall open on Sundays.
