I really like Trader Joe's. It has a lot of items that would ordinarily be really pricey elsewhere ie flowers, soy ice cream, cheese, wine and gluten free items.
Its not really ideal for those that like to make a lot of things from scratch as its more of a specialty retailer. I would say its a pretty good place to go for those who don't really like or don't have time to cook, are single, or want the finer things in life for dirt cheap. I'm sold.
