I had read about Konoba Malta here on TA and our group decided we wanted to eat there when we took a daytrip to Korcula from nearby Orebic where we were staying.
Others have already given detailed instructions on how to reach this restaurant - its a good idea to take them with you, as we did, as it is well off the main road. Its a very rustic place in a rural setting ... the owner lives on site. If you want a traditional Croatian experience this is a great place to try. Don't expect five star service - it is how it is.
We decided to head straight to the restaurant after getting off the ferry to see if it would be open for lunch. Good decision because we were able to order the Peka, (note if you are travelling "out" of season you must order the Peka in advance) for lunch and whilst we were talking with the owner in a mixed form of English/Croatian/Italian he insisted we have some liquers ... and not just one! He is a very friendly generous man who clearly enjoys his life and making his customers happy.
We went off to explore Korcula town and afterwards we returned for a late lunch, again greeted by the owner offering us home made liquers - self service - I think there were about 6 or 7 to choose from. He also took us to the traditional outdoor kitchen and showed us the peka cooking under the bell - it smelled divine and we knew we were in for something special.
We had the starter of home made prosciutto and hams and cheeses ... they were the best I have eaten in Croatia together with lovely crusty bread. Followed by the peka (a selection of meats and vegetables - I think potatoes, zucchini, onions and peppers). It is cooked with plenty of oil - its not a light meal at all, but bread helps soak it up, extremely tasty.
After lunch the owner took my 10 year old son down to his fruit trees and insisted my son pick some ripe apricots to take away with him - many of them actually... He then went off on his scooter returning 10 minutes later with icecream which he proceeded to give us for dessert.
We visited on a week day in late June and were the only diners there. We so enjoyed our afternoon at Konoba Malta and the warm and friendly service provided by the owner.
