In my opinion, second best in Boston, just behind Regina. Not your typical cheese slice, but that’s what makes it great. There’s no way this thing is in the oven more than 5 minutes. Good amount of sauce and cheese but doesn’t get too sloppy. Sauce and cheese (which, as far as I can tell, is just some really great mozzarella), are so, so simple, yet so amazing. Sauce is almost definitely homemade. Nice crisp on the crust as well. Only downside is that this is NOT a pizza you want to order, gets far too soppy during the delivery time, but with that being said, the restaurant is awesome and has a great beer selection, as well as some great ice cream! If you’re doing pizza tourism in Boston, Picco is a must.
