The most important thing: Food

The people in Barcelona are on a seafood diet, which is probably the healthiest diet you can have. The kinds of things I have tried here are:

1. Calamari
2. Pulpo=Octopus
3. Prawns
4. Shrimp w/ heads
5. Meat Empanadas 
6. Fish
7. I also have had some sort of "pastel de atun," which I guess translates over to Tuna pie/cake. It was quite good.

I will keep adding to the list and make it a bit more specific...
