You'll find a big Italian influence . We were in Pula last year year. Pizza very good and cheap, Italian ice cream for the kids 50p and it's great. Lot's of meat and fish and shell fish. Very reasonable prices as well.
Wine is lovely but as the best bottle on the menu is about £10 try that, it is the same as a £40 bottle here. The cheap wine there is virtually undrinkable. Beer again is great, worth trying the more expensive stuff at £1.50 a pint, heaven in a glass.
We ate out every night and lunch as well most days, most we paid was for a 5 star meal ina fish restaurant on the marina and that was £50 for two adults,two kids, two beers a bottle of very nice wine and a tip.
You'll love it.
