Has anyone ever been to Barcelona and found the locations?

I've been playing around with Google Maps, looking for the various locations used in the movie. For me, the Holy Grail would be the shop with the awning that is below the apartment that David and Thomas (Yuen Biao and Jackie) are living in.

Barcelona looks like a very beautiful city and it has a fine history of films shot there. There are walking tours that are available for people with a love of film, to go and stroll through the locations used in their favourite movies. Seems like "Wheels on Meals" does not feature on those lists, which is a shame.
