There were lots of tourists and shops that specialized in selling them (us) various merchandise. Some of it was actually nice art.
The Picasso museum was well organized and showcased the 4 main life/art stages that Picasso went though. We both found this interesting since we were most familiar with his later blue and abstract works. But in the earlier stages his work was much more traditional.
After the museum we found the Cafe L'Acadamia Restaurant that had been recommended by a travel concerige. It was looked old world with stone walls and dark wood. We picked well and a bit decadent. The "sandwhich" of duck foils gras and black truffle mushrooms was probably the tastiest bite of or whole time in Spain. We regreted not having found this place earlier in our trip.
Our dinner that night was also excellent. Con Gracia was certainly as good as any Michelin Star Restaruant. We had the tasting menu accompanied by wine parings. The staff were warm, friendly and very knowledgable. When they noticed our obsession with wine they made sure we had special tastings. Certainly a destination must for Barcelona travellers.
