Smaller and more intimate than the famous 'La Rambla', this is a much more enjoyable street. Lots of little shops and bars to eat drink and (window-)shop.
Our favourite was Bar Nuria at #34 that I can't find here on Tripadvisor. The bacalau croquetas are to die for!
When travelling north-west, when you get to Carrer del Perú go one block south-west, then continue on Carrer de la Llacuna and Carrer de Rogent for another lovely pedestrianised shopping street.
