Sprouts is a decent place to find the typical health-food store selection of "corporate" organic foods like Amy's, but it doesn't have the atmosphere or selection of a Whole Foods or the fun choices that you will find at Trader Joe's. They have great prices on fresh veggies, though, and they are walking distance from my house so I end up shopping there often.
Their bulk selection is great, and you can often find good sale prices on all kinds of legumes, as anyone who has seen the fallout shelter level supply of beans in my pantry could confirm.
Their wine selection is overpriced and uninteresting.
Best advice I have is to buy fresh veggies and bulk items here, then go for the prepared foods and alcohol at Trader Joe's.
