Update again: I give them props for service. I called on a Saturday night with a crazy request to put the toppings of the pizza I ordered in the shape of a heart and they did it for no extra charge. I would have understood if they'd said it was too busy, but they did it with a smile.
Update: since writing my initial review, several other pizza places serving vegan pizza have opened in the Twin Cities. I am not changing my rating for Luce, but would rather go to Galactic these days.
The spinach salad is surprisingly good, and I recommend getting "The Luce" off of the specialty pizza menu, substituting spicy mock duck and rinotta.
This place is a treat. It's open very late, the pizza and sandwiches are good. The rinotta is awesome. They have a ton of different topping options for pizza, and the sandwiches have flavor. Not a place for the health conscious though. The cake (if they have a vegan variety) is usually good, they cut you a huge slice. Beware of the frosting though, it's so sweet, after about half a piece my teeth are begging for mercy.
