i just came back a few months ago. we had the BEST lobster paella at casa majos. it was recommended by someone at our hotel. http://www.canmajo.es/ i agree with Toomz, shopping is great on passeig de gracia. and i did the bus turistic too. it helped us navigate through the city without worrying about getting lost. it stops at all the major tourist attractions. hope you have a great time!
