Overall it's very good food, with ambiance and service to make it a nice full-package experience.
The service is excellent with just the right attention to detail without being overbearing. The menu is moderately pricey, but it was all worth the price. This is not a quick meal - plan for Spuntini when you have time for the ambiance, the wine list and good conversation. Nice private areas for larger groups as well as small romantic tables. Have tried the grilled octopus app (tender and tasty), had bites of a couple of the salads (not swimming in dressing which is my biggest peeve), tried a few bites of several pasta dishes (all cooked perfectly and sauces were divine), and a sea bass that was cooked and flavored to perfection. You also can't beat the sardines if you crave salty and interesting. And the thin pizzas are not wimpy thin - nice heft without being too soggy.
I'd definitely go back with a large or small group.
