It's the best way to order by the slice, soak in that classic pizzeria energy, and mingle with the crowd. We stood at the counter and tried the Mozzarella and the Fugazzeta. As a New Yorker who swears by thin crust, this thick, airy, Sicilian-style like pizza is a totally different beast, but I definitely understand the appeal. The Fugazzeta was a completely new experience for me. It's essentially a heavy base of dough and infused cheese buried under a massive layer of onions. It's rich and delicious, but the classic Mozzarella slice ended up being my favorite, perfectly balancing salty cheese with a slightly sweet tomato sauce. Come hungry because this pizza is no joke; it is very heavy, and two slices will easily fill you up. Overall, it's a solid spot worth visiting to experience a local staple, but don't expect a life-changing slice.

I also appreciated that you can order individual slices of specific flavors and sit down to enjoy them. We had a slice of Margherita and another with sweet red peppers and green olives. Both were gooey with cheese and absolutely delicious. We also shared a beef empanada, which was fantastic. Most of the customers seemed to be locals, but we even saw a group come in with carry-on suitcases, so clearly this place is a must-visit! The staff was friendly and patient, even with our limited Spanish. Just a note: Argentine cheese tends to be softer and fresher than what we're used to, so even if you are not lactose, there's a small chance you maybe here in Argentina.
