It might have a different address, but La Piccol Casa is the same gem it has always been, perhaps a little more brilliant. The larger, more elegant reincarnation reopened at 410 West Boston Post Roadin Mamaroneck on May 5. It boasts an expanded menu, a more extensive wine list and valet parking on the weekend. Longtime patrons are especially pleased that the little restaurant that could still offers the great big flavor they have relished for 12 years. Owner and Chef Walter Ricci’s unwavering commitment to his kitchen is evident in every dish. Not only does he cook each one personally, he also heads to Hunts Point a few times a week to select meat, fish and vegetables himself.
