Dish Osteria is one of the best dining experiences I have had since moving to Pittsburgh. The food is very well prepared and literally everything was delicious. We had the spaghetti frutti di mare, the rigatoni and the grigliata pesce. You could not go wrong with any of these and it will be hard to decide which one to get next time. The service was very attentive but not annoying. The only bad thing is the lack of nearby parking but it's definitely worth the extra effort!
