I've been to Cugino's a whole lot and here are my thoughts. The pizza there is absolutely the best NYC style pizza in town, hands down. Not only is the pizza excellent, but its consistently excellent. Some places wander in terms of quality, but Cugino's pizza has been great every time. The other food on the menu is real good as well, (I particularly like the chicken parm hero), but it's the pizza that is the big draw.
The other real strong point about Cugino's is the deli. They have a wide variety of products like Italian cold cuts, fresh cheese, and other on the shelf products that are not easily found elsewhere in the valley.
Cugino's is a fantastic place to drop by for lunch or a quick dinner and always recommend it to anyone who will listen.
