There is a Food-4-Less at Euclid and Katella, just a short hop from DLR. Also, there is an Albertsons at Brookhurst and Katella which is a little farther down. (If you don't mind angry picketers waving signs in your face and begging you to go somewhere else....personally, I'm loving the empty stores with no lines and the replacement checkers seem to be doing okay.)
