En route to Portugal we stopped in Barcelona. I lived there for a year when I was 19, and I am glad I was able to appreciate the hard-partying-up-all-night lifestyle before I became a “disgusting old ghost” last month.
La Boqueria is a completely authentic sort of market, while also being insanely touristy place. It is a dreamy place of piled meats, fruits, vegetables and fish.
When I go to the supermarket, I generally find myself going from dairy/meats/cheeses on the left to grains/veggies on the right. La Boqueria cuts the crap and takes the best non-processed foods part of a supermarket and smooshes them together.
