Walk up to the counter, but don't order yet. You can't possibly know what you want. Try a few first. Try the Cassata if they have it - where the orange zings through the creamy countered against the dark chocolate. Or the Whiskey Pecan, which is such a balanced mix of flavors it kind of makes you wonder how people ate pecan ice cream without whiskey before. Or the Dolce Neve (It means fresh snow in Italian), where the slight kick of lemon zest livens up the sweet cream. It's like a playground in there, and it's important to try out all the swings.
The small size is ridiculously inexpensive, and is about as much gelato as I could hold. As is traditional with gelato you can mix whatever you'd like into that cup. I think the standard is two flavors, but I'd imagine Leo would let you go with three if you wanted. He not only graciously accommodated my kid's request for the gelato in a cup with a cone, he explained to her that in Milan, they called that a Pinocchio, because the cone looks just like Pinocchio's cap.
South First keeps getting better - Sugar Mamas got a little bigger and (I didn't think this could happen) a little better. Once Over has settled in even deeper and the patio feels even further from the middle of town than it did. Elizabeth Street Cafe is still making my favorite breakfast in town. And now Dolce Neve. I can't think of a better stretch of food, anywhere.
