This is my favourite restaurant, or better to call it bistro/pizzeria in the town and I'm local ;)
They serve Italian dishes mostly, pizzas, pastas, salads, meat and fish dishes in really nice, small place with professional staff. Be sure to reserve in advance.
I also use it for take away and delivery at least once a week while in office.
For all people coming to Mostar, if you are fan of Italian food this is the best place for you.
