Time Out says
Homemade Greek honey donuts—basically a far superior take on the Dunkin’ Donuts munchkin—are the perfect way to satisfy a sugar hankering without going overboard. And Gre.co, the newish fast-casual Greek restaurant in the Back Bay, is the quickest way to get your fix. Choose among five varieties, including the Yaya’s (hazelnut praline, Oreo cookies,) and the Golpho (caramel, almonds, sea salt). Or you can go (doh)nuts and fashion your own, choosing from toppings like dark chocolate, pistachios, coconut flakes and walnuts.
