Actually and generally it's well know that Spain has good food.

however, it doesn't mean everytying must be perfect, my opinion only. hehe.  I like their food, especially their seafood, very fresh and yummy.  It's probably that you came across some food that wasn't that good, quite possible, but I wouldn't say that just because the smell of the fryied fish wasn't that good, their food wasn't good in general. Right?
