In my city, there are several malls, and almost all have been updated. Grocery store options abound:
Vons (Safeway), Albertsons, Trader Joe's, Fresh & Easy, Walmart, Stater Bros., a few health foods/whole foods types.
The newest is Walmart Neighborhood Market, which is putting price pressure on the others.
I haven't seen it yet, but soon I expect old malls to be demolished, in favor of other uses. Maybe government housing projects.
