Don't trust or even taste this kind of s**t that some restaurants offers you in the Ramblas and near there, or in a lot of touristic places called PAELLA D'OR. It's a kind of half-prepared paella, quite similar as a fast food meal. Don't try it! thanks.
If you want a paella, always is beter when you go to the bar or a restaurant (maybe you can check close to your place/hotel), and you request it to make it to you (where it's offered). Usually you go in the morning and you ask your paella for an approximately hour. Is a dish that takes 1'30 hour at least! to be done. So, if you ask a Paella d'or, you will see how runs the spanish fast food.
