woha fail spelling in title...no way to edit, sorry :)

Also would you have recommendation for nice pieces of architecture to visit on a one day trip from there?

For tapas - La Bodegueta Provecena or Tapaç 24

... it's more about Catalan architects than projects but there are some new things built in the capital in the last years - google maps links included

ah, and most projects -in the right menu- have a pro review linked from The Architectural Review's - best arch magazine in Europe? - archives stored in findarticles.com

Taller de Tapas (Carrer de l'Argenteria 51)

It's in the El Born district where there's generally a lot of good stuff I seem to remember. Also, for that late night Absinthe, go to Bar Marsella (off La Rambla, in true Spanish style opens at midnight).

sagrada familia is easily one of the most impressive structures I have ever seen. its a definate must to climb (or take the added elevators) to the upper levels

Montserrat for an old school church outside the city and for Sangria you must go to La Oveja Negra.
