With dozens of great restaurants located on or near Broadway in Saratoga Springs, who would think to discover one in the Price Chopper plaza on Ballston Avenue? Perhaps you’ve spotted the place, wedged between a mattress store and Quarters, a neighborhood bar; its simple electric signs announcing “Pizza” and “Café” in red letters are that visible from the road. Perhaps you’ve seen the other sign, “Mama Mia’s,” and thought it must be one in a chain of pizza parlors, the likes of which can be found in any shopping plaza in the region. As you approach the restaurant, the first tip-off that this might not be one of those all-too familiar pizzerias is the six- foot-tall plaster statue of a chef standing outside the front door holding a sign that reads “Open.” Except for his size, he’s nothing special either, as this portly puffy-cheeked chef-figure has become ubiquitous as a restaurant-decorating motif. But then you spy “Giuseppe” printed neatly on his hatband. That’s the name of the owner, Giuseppe Grisio, from Bari, Italy. And a picture of his 78-year-old mother Giovanna, who lives in Italy, is depicted on the restaurant window.
