I’ve been in Rovinj many times, but Ulika one is the best!
This little restaurant with just 3 tables outside and only a few more inside in a side street is absolutely fantastic. The owner is a diva but is extremely friendly and always surprises with tasty and creative dishes based on a fusion of local Istrian and international influences. The atmosphere is very relaxed even when the main Streets are packed with tourists. Prices are higher than the average but I find it still fair and the food and atmosphere are worth every penny.
