One word... AMAZING!
My family and I took a trip from our summer house in the Adirondack's to Montreal last summer. A hotel valet recommended this place to us.
Fish soup is possibly the best soup i have ever had at any restaurant. All the food was good.
Service was excellent however at times it felt as if the servers were hovering over you and the water glasses never were less than 3/4 full.
Overall, Casa Napoli is an amazing restaurant. GO! You won't regret it.
