Mmmm! That freshly defrosted taste and texture!

I'm not sure if Paellador actually have restaurants, it's a brand of pre-prepared paellas that mediocre restaurants can serve to their undemanding clients. Like having a list of Frigo ice-cream desserts. It just shows how bad paellas can be if restaurants feel it worthwhile to display the Paellador logo to entice their customers, obviously it ensures a degree of quality/consistency, just like a Big Mac does.

(EDIT TO ADD and alanw beat me to the explanation!)
