Restaurant Djudja and Mate in Vid is a lovely place. One of my favorite in Croatia. It is not a fancy place. It doesn't offer the most extensive wine list or creative cuisine and famous, young chefs.
We often visit restaurant Kapetanova Kuca. It's one of three restaurants in Mali Ston, a little village at Peljesac peninsula, famed for mussels, oysters and other seafood cultivated and harvested right there, in Ston Bay. Other two restaurants are Bota Sare, and Koruna.
I had another great experience – Extra Virgine Olive Oil Tasting in Istria. I went for olive oil tasting at Belic Family. Belic Family are one of the best olive oil producers in Istria. They produce 11 different extra virgin olive oils under the brand Oleum Viride. The name itself was used by ancient Romans for olive oil produced from medium ripe olives.
