We were already crazy about Copper Star before we discovered they sell their own locally grown, house-roasted coffee beans. At first, we worried that owning a bag might keep us from the cozy confines of Copper Star, where the staff is so nice to us and the homemade bagels are so fresh and tasty. But even after dragging home a bagful of his mellow, rich beans, we found that we kept visiting Bill Sandweg's swell coffee shop as often as we could. As tasty as our home-brewed Copper Star is, as both a hot latte and a chilly iced coffee, we can't stay away from our favorite corner cafe.
