After two failed restaurant ventures at 136 Main St., owners of the recently opened Spiga are hoping to buck the trend that first sank Tuscan and more recently, Barolo. And if foot traffic and response are early indicators, it seems as though the third time is indeed the charm. Since its soft opening earlier this month, Spiga has New Canaan denizens abuzz with favorable and enthusiastic praise for their Northern Italian cuisine. The motto at Spiga is ‘Eat – Drink – Play,’ and while I personally can’t speak for the ‘play’ part of it there is something for everyone on the voluminous menu for diners of all types. Gone are Barolo’s sectioned dining areas, walk-in wine refrigerator and antipasti bar, replaced with a large, open space replete with oversized booths, communal tables with seating for 130 people.
