Paul Revere's 5

Great pizza for a pizza chain, and cheaper than most of the competitors. The Terminator and breadsticks could be the best pizza deal in existance. 

EDIT: They also have $1 slices during lunch. This is by far the best lunch deal within walking distance of my office. I can be full for $4. If I go anywhere else, I get half as much food for a minimum of $5.

UPDATE: They no longer have the $1 slices over lunch, they are $1.25, the same as their evening price, which still isn't bad.
