Da Vinci's, on Route 45 in Chestnut Ridge, is another great choice for casual Italian in Rockland. There is a restaurant, which is quite casual, and a pizza place, which is supremly casual, located next to each other.
At the restaurant, I HIGHLY reccomend the chicken parm. It is very light, very tasty, and VERY, very good.
The pizza is also great, although I have not enjoyed it as take out as much as I enjoy it when I eat in the location (perhaps it is a mental thing!). They often have a lot of variety, including baked ziti pizza and sicilian.
