L'arte del Gelato is my favorite shop for gelato in the city, but there is no denying that Grom turns out excellent frappés ($6.25) all summer long. Your choice of any gelato or sorbet blended with whole milk, organic of course. The serving size is small, considering the price, but so creamy and indulgent you really won't need any more. I like it best with their Caffé Espesso gelato made with Guatemala Genuina Antigua coffee. The resulting frappé isn't thick enough to stand a straw, but the richness comes from the flavor—a bold, heady coffee, and perfectly chilly. Feeling even more indulgent? Top off with fresh whipped cream for $0.55.
