The best GF grocery store selection I have seen. aisle 17
Vons has a selection of gluten free items like Udi's bread, pizza, muffins, etc. in the frozen section. They have several choices of gluten free pasta, including one from their own "Eating Right" generic brand that tastes good and is reasonably priced. They have "gluten free" tags around the store under prices in the shelves for many items to help you find things.
