Visiting world-famous La Boqueria food market in Barcelona (& comapring it to less known Sant Andreu Market)

This was one of the things I looked most forward to. Since I've seen most of the architectural pieces of Barcelona already couple of years ago, food markets were on top of my list. And maaan, I wasn't disappointed. It's crazy over there. Sooooo much food and snacks of various types...and soooo many people shouting over each other :D
