There are three standout Italian eateries in, or near, the Cherry City.
My favorite is DaVinci. It's intimate, warm and elegant. The food is stellar and the service is perfect measured attentiveness which only comes from a blend of good training and instinctive human connectedness.
Next is Caruso's. (Actually in neighboring Keizer.) Their new location on the shore of Saats Lake is ideal for alfresco dining in summer and the interior is cozy and warm for drearier weather. The food is good. The wine list is well thought out and we've always found the service acceptable.
Then we have Gamberetti's. Recently relocated to the cavernous venue in Pringle Park Plaza overlooking Pringle Creek. It too has Parisian sidewalk cafe tables outside with the breeze, whispering brook and ducks (which, mercifully keep their distance). Others have suggested that the food can be spotty. We have been here a number of times and feel it's been consistently good as has been the service. I recommend it without hesitation.
I have not been to the new Spaghetti Warehouse digs, but am told since they moved to the gentrified location that their menu has been refined somewhat. It may well be worth a look.
