Excellent selection of whole foods and organic. Good sales too. They are a bit pricey, though this is pretty much the norm for all health food these days and I think overall that Common Ground is cheaper than Strawberry Fields.
They recently expanded and have a great salad bar along with pizza and sandwiches. A small but nice selection of beers and wine have also been added since the expansion.
Part of what makes this place so great is the people. I shop here often and the employees genuinely seem like they enjoy their jobs. They are easy to talk to, very helpful and kind.
One of my favorite places in the area....go check 'em out!
