Every time I go to Santa Monica I make it a point to go to Viva La Vegan, an all vegan grocery store. As helpful as the Is It Vegan App is, it cannot compare with not having to read a label to know if an item is vegan. The store has quite a variety of items ranging from biodegradable bamboo toothbrushes to vegan seafood. In addition to veganized versions of meat products, Viva La Vegan has the healthiest options around for many packaged goods such as cashew butter that only contains cashews - something I have been trying to find for awhile.
In my opinion, Field Roast, makes the best tasting vegan fake meat products. All of their items are sold at Viva La Vegan and their products are increasingly sold at major sports stadiums! I'd highly recommend the apple sage sausage in particular.
Although I don't bake exclusively gluten free, I often do and greatly appreciate the wide variety gluten free flours and other baking items available at Viva La Vegan. During this past trip I bought white rice flour so I can make sweet potato caramel chocolate chip blondies. I really appreciate how often vegan stores, vegan bloggers, and vegan restaurants are very cognizant of food allergies.
