I live in Mallorca (in the Balearic islands in the Mediterranean - as you can imagine I don't usually speak english, so this explain the funny expressions I use in the forum, lol).
Galicia it's on the other side of the country, and it is a nice place, with beautiful landscapes and incredible food (seafood, specially) and wines (mostly the famed albariño white wine).
I have lots of friends from there, and they usually speak both spanish (castellano) and galego (their own language), as we majorcan speak spanish and our mother tongue català (in our own balearic dialects).
From Galicia, the desserts I prefer are the filloas (some kind of crêpes) and tarta de Santiago (Santiago's cake or St. James' cake).
And gallegos you can find all around the world. Hahaha. I have never travelled to any country where I didn't find some.
