You beat me to it! It's so important it bears repeating:
If you are in Spain and you see this logo in front of a restaurant: http://www.mundofranquicia.com/mfc/i...q/logo4490.gif
RUN, do not walk, away.
Especially outside of Valencia, you will see this crap served everywhere. It comes frozen in a bag and it is nasty. I don't think any Spaniards would ever eat the stuff but thousands of unsuspecting tourists fall victim every year. It isn't a restaurant chain, rather it's a brand of frozen food. They give out big colorful posters to the restaurants that buy it so they can trap unwary customers.
I'm not a fan of any paella myself, though sometimes you have to eat what's put in front of you.
Fideuà, on the other hand, I like. Probably because it's loaded up with all i oli.
