Alright, big declaration ahead. Otto is one of my favorite pizzerias I have ever been to. They use creative, wholesome ingredients and I can always count on their consistency. I especially love their Otto four cheese and three cheese tortellini slices. They started out in Portland, ME and have branched out with 4 locations around Boston. I first tried Otto in the Harvard Square location and have been hooked ever since. Although the pizza is more expensive than most, it is a great way to treat yourself every now and then. You can order take-out (which is what I usually do) or eat at one of their locations. I most recently had their tortellini pizza (see below) and it was everything I expected. The sweetness from the tomato sauce paired with a thin, yet substantial crust completely highlighted the savory tortellini and fresh cheese. Enjoy!
