Time Out says
Run by the same management as the Lokanda Peskarija, this is one of the best pizzerias in town. It certainly serves the biggest pizzas. It's a simple wooden venue at the Pile Gate end of the Old Town, providing a straightforward 50kn dining fix. If you don't fancy pizza, there's also grilled meats to choose from. With tables outside on a summer's eve, Mea Culpa makes for a pleasant, cheap and communal dining choice.
