In Florence, Italy, a city not known for its lack of good things to eat, people apparently line up all day long for sandwiches at the Mazzanti family's All'antico Vinaio shops, the first of which opened nearly 30 years ago. For a while now, though, Tommaso Mazzanti (who pretty much runs things these days) has said he's wanted to bring his family's overstuffed magic to New York City—he's proud of his creations and wants to explore the possibility of landing a permanent location here in the US.

Conveniently enough, the Mazzanti clan is friendly with Lidia and Joe Bastianich, who own Greenwich Village mainstay Otto, and now for one month only, All'antico Vinaio has set up shop there. From noon on Monday through Thursday, and 11:30 a.m. on Friday through Sunday, Mazzanti and his charming, talented crew will be serving five of their signature sandwiches (plus an occasional special) every day until the fresh-baked focaccia runs out.

I had the opportunity to eat the entire All'antico Vinaio menu the other evening, and all five are terrific, exploding with big flavors from the impeccably-sourced and/or housemade ingredients. Sandwich fiends should make whatever effort is necessary to get here at some point this month to see what all the Florentine fuss is about.

Mazzanti's most basic creation is probably La Summer: Prosciutto Toscano sliced to translucence, chewy chunks of Bufula Mozzarella, bright Pomodoro sauce, basil leaves, olive oil, and balsamic vinegar. Like all of his sandwiches here, it's both generously portioned and exceptionally well balanced. And of course, delicious.

La Boss is a richer take on the prosciutto sandwich, the meat here covered in both pecorino and truffle cream. If you like gorgonzola, definitely get La Washington Square Park, which pairs the that cheese's sharp tang with a wonderfully oily lardo, truffle cream, a few slices of pear, and crisp-fried zucchini, complete with blossoms.

The latter might have been my overall favorite of the evening, or maybe it was La Dante I liked best, which unleashed the full funk of a fine Cappocolo with creamy Stracchino cheese and a bit of arugula. And the surprisingly spicy, porchetta-stuffed L'Inferno is great too, allegedly named such because Ron Howard used to frequent the shop when he was filming the movie Inferno.

The All'antico Vinaio pop-up functions discreetly from Otto proper. The sandwich counter is set toward the back of the restaurant's bar/enoteca area, and you'll order and pay right there, then grab a place to sit somewhere. If it's a pleasant day, of course, the pro move is to bring your haul around the corner and a block away to Washington Square Park for a picnic.

All'antico Vinaio is located within Otto, at One Fifth Avenue and Eighth Street, through July 13th.
