I'm a huge fan of Heinen's. This location is a quick stop on my way home from work (literally across the street). I don't mind that it's slightly more expensive than other grocery chains because overall everything is better. The selection of produce is always fresh. They have a nice selection of wine and cheeses. They regularly stock a lot of local finds that I would otherwise not know about. And the bread is awesome.
Not such a fan of the prepared food section though, it's a little hit or miss for me there. When I do need a lunch item from there, I usually reach for the soups.
