If you are not a vegetarian I would go to "Botin" and try their "Cochinillo" (suckling pig) or their roasted lamb (cordero). The restaurant is situated in Cuchilleros st (not in Toledo st!) and it is not one of the oldest restaurants in the world, it is simply the OLDEST (check it out in the guiness book).

Have a good time!
