Banh Mi in Redondo Beach, Torrance, Lawndale Area?
Daily Wok, in the old Lori's location, now serves Vietnamese food. Bahn mi is OK if you need a fix an you're in the neighborhood. Corner of Western and Gardena.
I haven't been to the other pho restaurants in the area to sample their sandwiches, so I'll refrain from recommending anything else for now. You could do some recon and let us know what you find...
