Bar Boulud is scooping up some seasonal spirit with the return of their Back Bay Summer Sundaes. Whether you’re stopping in for a break from the heat or looking for a treat to bring along on your stroll, their homemade ice cream and custom toppings are just the thing to keep your sweet tooth cool. Try a Hazelnut Rocher (hazelnut gelato with praline pirouette and Nutella), a La Joie (coconut sorbet with chocolate ice cream, candied almonds, and toasted coconut), or the Peach Melba (peach sorbet, vanilla ice cream, vanilla chantilly), all available a la carte for dine in or take-out.
