Food: Els Balconet sources its food locally and designs the menu around that idea. The food is wonderful and fresh (and you can feel pretty good about eating the fish if you worry about overfishing).
Wine: A really nice selection of local wines. So fun to eat and drink so "locally" here. Had a 100% xarel.lo from Catalan. Perfect with seafood.
My take: When in Cadaques, go to Els Balconet! Ask to sit on the top floor terrace.
