Have to add my stars to the pile!
Funky, unpretentious, great food! The Porchetta is simply the best sandwich I've ever had, anywhere, ever. I recently started buying their bread - perhaps the best in the valley, and on a par with Acme Bakery in the Bay Area.
To those who said this place is not 'authentic' ... I was there during the World Cup (soccer) in 2012 when Italy happened to be playing, and the place was full of Italian-flag-draped young men, all cheering and shouting in Italian. The owners were out in force too!
My g/f loves the 'trippa' (tripe), a seasonal special they do. I also love the way you help yourself to beers - you just walk up to the cooler and take what you want, and pay at the end. Very homey!
