There are amazing restaurants along Ammoudi Bay in Oia! Dimitris Ammoudi Tavern, Sunset in Ammoudi (sunset-ammoudi.gr), and Ammoudi Fish Tavern (ammoudisantorini.com) are all among the most highly recommended. This would be a great dinner option if staying in Santorini a couple days before or after the wedding.
