I was reading the Sunday LA Times today and saw an ad for ALDI in the help wanted section. It looks like they're opening up several stores (8 to 10?) from the SFV to Orange.
It's too much of a haul for us to make on a regular basis (I'm not driving 200 miles round-trip to save on groceries), but I'll add it to the list of stops for when we do a long-range shopping trip.
The ALDI website doesn't list the LA-area stores yet, but they should be coming soon....
