Tasty pizza - Edit
My friend who is NOT a vegan cheese fan made it thru almost 3 slices before she started picking it off! As a vegan cheese lover myself, I thought it melted quite well and complimented the margherita pizza quite well.

Good pizza - Edit
The sweet potato pizza is pretty good! Otto's pizzas are best steaming hot so take out is a little tricky

Soo good - Edit
I ordered the small build your own vegan pizza with mushroom and olive. It was very good! The crust is very thin which we liked and the sauce and vegan cheese tasted great. We had the food delivered so I can’t comment on the actual store.

Flavorful Vegan Options - Edit
Delicious vegan options. My delivery order came sooner than predicted and the pizzas were still hot and crisp. I had two vegan pies and a very fresh house salad (I used my own dressing).
Read more- The first pizza had cauliflower and mushrooms with vegan (Violife) cheese and no sauce. It was rich and savory, and the veggies were really flavorful and peppery.
- The second was a build-your-own with red sauce, vegan cheese, spinach, vidalia onion, green pepper & basil. I added my own black olives at home because I'm not a fan of kalamatas. Classic zesty flavors, wonderful combo. Next time I'll add mushrooms, too.
Very happy with my first meal from Otto. I did find the build-your-own to be quite pricey - $33.50 for my large veggie pizza, before tax, tip & delivery. But it's hard to find vegan options this tasty so I'm sure I'll be back.
Pros: Good vegan options , Highly customizable , Fresh
Cons: Expensive , Crust is just okay

So many options! - Edit
Settled on Otto because they have so many more vegan options that Flatbread, Bonobo and Portland Pie. I got the gluten free 12", which I assume is vegan since it's listed as an option in the vegan menu (Portland Pie's gf crust has egg.) Ordered the mushroom cauliflower, light on the cheese. I rarely eat pizza as I'm whole food plant based and don't often get anything processed. So this was a treat. The crust is thinner and crisper than Flatbread's, but yummy. Overall, I'm happy with my choice. I'm the type when I make pizza at home load on the toppings heavily to maximize veggies. I have yet to find a pizza place that does this (Portland Pie comes closest.) I'll definitely return to Otto though. Husband had the veggie special which was easily made vegan by swapping out the cheese (sweet potato polenta - very light on the small bits of polenta.)

Prices are very reasonable for vegan and gf upgrades.
Pros: Vegan options, Friendly staff

Good Pizza - Edit
Was good, but not my favourite pie (I prefer some other places in Portland for a vegan pizza). But really appreciate the vegan options!

Expensive Pie - Edit
They always have a vegan special. The pizza is good and well coated in vegan cheese, unlike a a few pizza joints in Maine.

When they do a vegan special, they do it right! - Edit
I’ve been (drunkenly) getting slices at Otto’s for years... always the cheese-less with marinara and veggies. Always did the trick because their sauce and crust are so good. However, I stopped in August 2019 for their beyond meat special which tasted just like a cheeseburger pizza.... it was INCREDIBLE. Seasoned perfectly and just the right amount of vegan cheese, meat, and veggies. You did have to ask for vegan cheese, but the waitress said it was so popular that they are considering adding it to the permanent menu! Ask for it even if you don’t see it!!! And make sure to specify vegan cheese.

Cons: Only a couple options total, Not entirely vegan

Nice staff, not great taste. - Edit
Nice staff, not great taste. The gluten free crust was delicious but the vegan cheese and other toppings were not satisfying. I ended up scraping off most of the topping and just eating the crust.

We ordered the plain cheese just to really see what this pizza had to offer and it was delicious. So many toppings to choose from as well.
