Trader Joe's started out as a California chain and thank goodness they saw the wisdom in expanding. They offer all kinds of unsual and gourmet foods at regular food prices, sometimes lower. PLUS they have samples out all the time and you should always try these because it'll open your eyes to things you wouldn't have bought before (at least it works that way with me).
They don't have a huge produce department but they make up for that in other ways, like the big selection of ready made deli salads and things in the fridge section---great place to pick up lunch.
Their checkout is very efficient and the employees all wear Hawaiian shirts and are very helpful and friendly. Just a great place to buy food, period.
