La Boqueria, Barcelona

Love this market, it's super busy as you'd expect, with not too much space to eat what you buy, but the quality is great in general everywhere here. You'll get food from everywhere and usually there's a fish market in the centre too (it wasn't open on the Monday when we went, but that just left us a little more space). You can buy dishes to eat there, or items to take home. Slightly more expensive of course, and very touristy, but a very large, high market area - excellent to wander around in, grab some delicacies and a beer or 2.

The market was a fun experience. I recommend walking the entire market before choosing who to buy from because a lot of the vendors offer the same things for slightly different prices. But you can choose your own adventure. You can grab a snack or eat a whole meal. There aren't many seats in the market itself, but there is a small plaza behind it with some benches where you can take your goodies.
