As for the locals, the Serifians, they are generally unobtrusive, but when approached are welcoming and helpful, and more than happy to offer you a fruit from their tree or whatever they have in their kitchen.
So, for a taste of something a little different, do not hesitate - try Serifos, you will surely not be disappointed!
