I love the restaurants where they constantly make rounds with trays of something freshly made, and many times it's a bit of a guess what it could be as they fly by so quick. You just pinch them off the tray, hope you got something you wanted, then stack up the plates and pay per stack at the end.
Also did you know tapas is called pinchos/pinxos in the northern regions of Basque and Navarre? They have been known to get a little annoyed if you ask for tapas there..
