Hi Fi Pizza
Mass Ave next to the Middle East
Cambridge, MA
real late (3-4am)
Boston is a pretty severely pizza-challenged city, but this place has hit the spot so many times after outings in Central Square that although I've never tried it, I bet it's not even that bad sober.
Oh, and if you're ever tempted by Little Stevie's down on Boylston in Boston, try the 20 minute hike up Mass Ave to Central Square. If you're so drunk that you'd like Stevie's pizza, or fail to notice the crowd just out of the fake ID convention, the walk will do you some good.
