There’s a reason you’ll catch wind of conversations in unfamiliar tongues as you wander the aisles at Formaggio Kitchen: This is where Boston’s European expats come to find the best cheeses from their homelands. Formaggio runs a thriving school and trains some of the city’s best mongers—but what really shines is their singular selection. In order to stock cheeses you can’t find anywhere else, owners Ihsan and Valerie Gurdal travel to tiny villages in search of family farms to partner with (talk about a dream job). Many of the artisan cheeses they introduce are in America for the very first time. Of course, they also stock some of the best domestic and local cheeses, too. Just don’t expect to leave here with only dairy in tow; the wine and grocery selections at each location (West Cambridge, Kendall, and the South End) are equally tempting.
