This trip report is a bit late since we went last May, but hopefully it's useful. We spent 9 days driving from the north (Rovinj) to the south (Dubronvik) and loved it!
Lovor Grill, Rovinj (lunch): We rode our bikes here and stopped as it was where we wanted to turn around. Had burgers and local fried fish (sardines) -- the meal was nothing special.
Kantinon, Rovinj (dinner): Our concierge recommended this restaurant as it's the more casual restaurant of a well-known local chef. Cool pubby atmosphere, interesting menu but the flavors were a bit boring in the end.
Pod Napun, Motovun (lunch): Lovely lunch on an outdoors terrace with expansive views of the truffle forests at the base of the town. Gigantic sandwiches and good truffle pasta & cheese.
Hotel Jezero Restaurant, Plitvice Lakes (dinner): Big unattractive hotel restaurant. We looked forward to trying the local trout, but while it tasted very fresh, the flavors didn't stand out. Overall fine but nothing special.
Konoba TRS, Trogir (dinner): Such a pretty restaurant on the inside, with stone walls and white billowy fabric on the ceiling. The menu is quite large and sounded wonderful with many dishes we didn't see elsewhere, but many of the dishes didn't quite live up to the promise. The exception were the amazing fresh langoustines -- super fresh and sweet.
Konoba Menegro, Hvar (lunch): The owner recommended that he chose the menu for us, which was a huge mistake. We received two fisherman's appetizers platters -- overpriced, too much of the same things, and honestly not that tasty. The other dishes were fine but the whole meal felt much more expensive than it should be. That said, it's in a cute little building along one of Hvar's many step-streets.
Konoba Gojava, Hvar (dinner): Without a doubt, the best meal of our trip. Lovely atmosphere, dining on the actual step-street looking down at Hvar harbor. The menu items were the same as through much of Dalmatia but everything had more pop. Risotto was delicious, as were the seafood stews. Langoustines not as tasty as TRS but overall an excellent meal.
Sucaraj (lunch): Can't remember the name of this restaurant but there weren't many in the tiny town of Sucaraj. This was on the other side of the harbor from the ferry dock. Had a delicious (and reasonably priced) seafood plate lunch of grilled fish, squid, scampi and langoustines.
Bota Sare, Ston (light dinner): Being hungry after climbing the Ston walls, we feasted on the local oysters, brodet, buzara. A bit pricey but satisfying.
Konoba Ribar, Dubrovnik (lunch): We wanted to like this restaurant but overall it was disappointing. The risotto was especially bad, being gummy and tasteless.
Restaurant Komin, Dubrovnik (dinner): Since we weren't able to get peka on Hvar, I searched for where we could get it in Dubrovnik and went out of way here, ordering both the veal peka and octopus peka. The veal peka was very rich and a bit dry. The octopus peka was mostly overcooked, being totally burnt in many areas, but the edible pieces were delicious. Not worth the trip from Old Town.
Restaurant Kapun, Dubrovnik (lunch): Our "Game of Thrones" tour guide recommended this nice restaurant right across from the church. Excellent meal, especially their signature capons. The truffle dessert sounds better than it actually is; avoid.
