One of the best grocery stores in Madison. Very clean, helpful staff, and excellent selection of products from high end meats and cheeses to all the normal dry goods.
I live on the east side so one of the only downsides is they don't have a Metcalfe's on this side of town. Anytime I am downtown or near hilldale, I make sure to get my groceries at Metcalfe's.
The one other thing I really like that I almost forgot was their support of local farmers/ingredients. Some of the items say how far they traveled to get to the store which is pretty cool.
