I've been to Mercurio's a few times, but Saturday I took my parents along for their first time. We ordered two pizza's between the three of us and my mom and I got gelato for dessert. We ordered a Quattro Formaggi and Margherita pies.
The only reason I give them four stars is because I'm not in love with the pizza but I am in love with the gelato. Staff is generally friendly, super young but nice and professional. They seem to enjoy working there. Again, gelato is amazing. This is my go-to for dessert.
I think there is better pizza in the city, Mercurio's pizzas are a little pricey (in my opinion) and I think you could get a better specialty pizza somewhere else in the city for the same price.
