Daphne's Greek Cafe out here in Los Angeles participates also; they are quick service greek...and delicious. (Edited by Moderator to indicate Daphne's no longer participates.)

Also, an El Pollo Loco here in North Hollywood participates; unfortunately they are an EPL that I have vowed never to go to again due to poor service.

EDIT: the EPL in NoHo does not participate, the one on Glenoaks in Glendale does (but there prices are about $.10-.20 higher than other EPL's).
