The best italian restaurant in Sacramento is not in Sacramento, but in El Dorado Hills about 20 minutes north on Highway 50 (towards Placerville).
I've dine there five times in the past year and have always been impressed by the quality of the food. Angelo Auriana, its executive chef, is passionate about his food and genuinely cares that his customers are enjoying themselves. His focus on using the best available fresh ingredients shows up on the dining table in the way of: fresh maine lobster served on a slice of mozzarella atop a heritage tomato topped with a balsamic vinegarette; foie gras tortelini topped with shaved white truffles (imported from italy at around $1800 a pound); a chilean sea bass that melts in your mouth; cuts of aged meat that exude flavor, and his risottos are also fantastic, once with tender veal cheeks and the other time with white truffles.
Excellent and reasonably price wine list; however, i usually bring my own and pay the very reasonable $15 corkage. Angelo and his wine manager, Nicky (Niccola) really appreciate fine wines, and will even, with sufficient notice and coaxing, do a wine dinner centered around special wines. Bring him your Lafites, Las Cases, Giancosa's, Bonne Mares, and TBA's ( or even BA's or ausleses) and Angelo's fantastic wine memoery and palate will deliver you a memorable meal. Masque certainly deserved being named by Gourment magazine last November as one of the best new restaurants in America.
