Famous is a well-known pizza place on Colfax. I've only gotten individual slices there, but they have a good deal on 2 huge slices and a drink for about $4. You pick from the already made slices that are out, and then they're heated up for you. It makes service extremely fast, and the pizza usually still tastes pretty fresh, even though it's not necessarily made fresh right then. All the pizza is pretty greasy, and has kind of a floppy-crust, New York taste to it. The pepperonis are very good, as they're a little spicy, and I highly recommend it over plain cheese. There is always plenty of seating, they usually have whatever popular sports game is on at the time on the TV, and the atmosphere is very casual.
Pros: New York style pizza, tasty pepperonis, big slices, and no waiting to order, pay, and eat!
Cons: Slices aren't necessarily the freshest, and are very greasy. They sometimes charge for drink refills.
