When I hear San Dimas I think about Bill & Ted's Excellent Adventure! I think I'm showing my age with that comment though.
I had Qdoba today for lunch - their children's naked chicken burrito is perfect - I get it without rice, so I get pinto Beans, grilled chicken, pico, salsa verde and a bit of sour cream. I get a side of chips and queso and just have a few chips - it's delicious and the perfect size. I can't finish all the beans but I pick out all the chicken and tomatoes. Plus it's only $4 and change and comes with a drink, too.
