L'asso is a funky and casual pizza restaurant a block of Little Italy's Mulberry Street. It offers some very unique and tasty pizza options--not traditional, but very recommendable. Come here for the tasty pizza, and you'll also eat at a place committed to healthy ingredients--organic unbleached flour, organic tomatoes and tomato sauce, hormone and antibiotic free chicken, etc.
We very much enjoyed the Tartufo pizza (portobello pesto, mushrooms, smoked mozzarella, rosemary & truffle oil), which was a surprise to me since I don't enjoy mushrooms. The pizza was covered with mushrooms and they were so mild and delicious that I had a second helping. We also ordered the Bufalina (tomato sauce, fresh tomatoes, uncooked buffalo mozzarella, oregano, basil & extra virgin olive oil), and it was also very good.
My only minor complaints: First, the place is a bit cramped; the table next to ours had to move their table so we could sit down. Second, L'asso's pizza crust is not very crisp--I prefer a somewhat more crispy crust, but L'asso's crust in keeping with NY pizza traditions.
I'd definitely be back. I've yet to have better pizza on the row of Italian restaurants a block away on Mulberry. L'asso is a great option if you don't need the old-school Italian ambiance common in Little Italy and prefer some different, tasty, organic options for your pizza.
