Awesome vegan pizzas! But I would recommend Ian's to anybody, meat eater or non.
I like the atmosphere, and that they're open until 2 or 3 am on weekends. I love the portabella mushrooms, artichokes, spinach, vegan "mozzarella" & "pepperoni"! It's great that most of the veggies are sourced locally and are seasonal/fresh. (Probably the meat and cheese is too? Idk)
Whether you get the dairy-based or non-dairy version, you really should try the mac&cheese pizza. I didn't think it sounded good at first either. I was wrong!
I think that like most other places they do jack up the prices for the vegan options, but that is kind of to be expected. Seems like otherwise Ian's prices are pretty good compared to say Glass Nickel or something. My roommate orders Ian's pepperoni and cheese pies all the time because they're apparently cheap and awesome.
My only real problem is that on Mondays, when they advertise that they have vegan pizza available by the slice during certain hours, they often do not have any at all. And sometimes they'll make one when you point out the fact that it's Monday, but it takes forever and kind of defeats the purpose. Then other times they will just tell you that they'll only make a vegan pie if you intend to buy the pie... That's not cool. Why do you advertise this thing if you're going to tell me you're not going to do that thing?
One other thing, they have repeatedly forgotten my drinks when I got delivery and ordered sodas! So if you order online I would seriously recommend calling them up and reminding them that you ordered a drink, or just don't bother. To be fair though, last time it happened I finally complained to the delivery guy and they gave me a $5 credit for my next order, as well as making a return trip to bring the drinks. So they did make good.
