The first time I passed this recently opened pizza emporium at One Union Square (6th & University) there was a line out the door. The second time, I was part of the line in my never-ending quest for a good lunch place. MOD stands for Made On Demand and they are quite speedy about it. You order your pizza and they put the ingredients on a partially baked crust (very thin, almost cracker-like), slap it in the oven and in about 5 minutes they magically call your name. The pizzas are all personal sized, I'd say about 10 inches but I'm just guessing.
The big thing is that you get your choice of ingredients, all for the same price: $5.54 (don't ask me why the 54 cent price point). They have 10 pre-named combinations, or you can just build your own from about 24 ingredients. A few extras are available: a standard salad of greens and roasted red peppers with sweet balsamic dressing for $3.54, a deluxe pizza salad for $5.54, and their own bread with fresh rosemary and red sauce for $2.54. Drinks include soft drinks, beer, and wine, along with hand spun milk shakes.
I had the mad dog #2 pizza that comes with their signature red sauce, mozzarella, pepperoni, italian sausage, and crumbled meatballs. It was very tasty and just right for my healthy appetite. They have a call-in number and encourage take-out orders. And yes, there's usually a line but it moves pretty fast.
