In case not clear: 4 categories of interest: make that 5:
-The uniquely Barcelona stuff you couldn't in 1000000 years stumble upon yourself (unless very lucky)
-Lamb, mutton, goat slow cooked style
-Anything I would not even know to ask about, but should definitely try.
With many thanks.
(Spanish/Catalan menu items untranslated are appreciated so I know what to look for)
