I was in Linz. I saw an Italian restaurant named Benaco. It seemed authentic. Thus, I decided to eat my dinner there.
In fact, I was a little hesitant since some Italian restaurants are run by non-Italian people and they do not serve good quality food.
Any way, this time, I was lucky. The pizza was delicious. They did not over-cook it, its ingredients were fresh. The indoor was decorated nicely. This restaurant is not far way from JKU.
