Central Market is more than just a grocery store. It has a very large selection of organic and natural foods and products. The quality of produce at the market is outstanding and the dairy products are not likely to spoil on you too quickly (they pull it a week before the sell by date).
They have a good selection of Asian foods; both fresh and packaged. It is probably the best selection outside of Seattle.
If you cannot find an item you are looking for at another store, they will often have it (and if not they are willing to order it for you).
Prices are a little high on some things, but the quality can be worth it and overall they are competitive with other grocery stores in the area.
