delicious food, super-friendly staff. we stopped at the mason jar for a late lunch en route to grand rapids. to ourgreatpleasure, we found the perfect anodyne to long hours of driving and some nasty chicago traffic: a sweet and soothing ambiance; friendly and welcoming staff; and really delicious, locally sourced food, skillfully prepared and served up in very generous portions. the mason jar thoroughly satisfied us foodies. we'll be back on our next trip to michigan!
