Boasting a bit more authentic charm compared to some of the competition around the corner, Delfin lays claim to being the oldest fish restaurant in town and has the unique distinction of being located in a 500 year-old former municipal building. The food is quite good - especially when accompanied by some cheap house wine - and the service friendly and unhurried, although our waiter didn't seem overly amused when we tried to order dolphin ('You don't have dolphin? But isn't delfin Slovene for dolphin?').
