$05 - $10
Nice little cafe, very good sandwiches (curry chicken, classic italian, etc). They have an especially nice setup for the powerbook/thinkpad-toting work-from-cafe crowd.
Call ahead if you can -- service can be very slow!
Pivotal Lunch Spots
Different lunch spots around the Pivotal Office on Market St in San Francisco.
I remember that first pivotal lunch when we knew it was more than lunch.
