Walking in evening in Barcelona

Would like to know the best areas to walk in the evening in Barcelona for window shopping, restaurants, music.
Not interested in crowds or loud party life areas.
Would like an area near like the Via Condotti in or Piazza Navoni Rome.

Welcome on the forum bbqbrisket :)

i've just moved here so not an expert

but maybe somewhere like passeig de gracia, which has lots of boutiques (mainly designer) and also restaurants/bars
