Authentic Italian restaurants in HCMC

There isn't a lack of Italian restaurants in HCMC but its hard to tell which is the most authentic.

Tried the pizza, pasta, lasagna & tiramisu at the Luna D'Autunno restaurant along Suong Nguyet Anh Street, which prides in its wood fired oven pizzas. As for its Tiramisu, I must say its not as good as the one I had at the Good Morning Vietnam restaurant.
