IN ELLSWORTH, MAINE, at Mr. Paperback in the Maine Coast Mall, there is a cafe so special that people come to it from miles around. They come for the homemade soups, great chili, Carpe Diem coffee, maine-made jams and jellies, and wide variety of vegetarian dishes. They come for the ambience, the great Maine art, the intriguing Maine crafts. They come for light dinners, and great Mexican dishes. And, finally, they come for the gracious and friendly service. As you travel Downeast, why not make it a point to come as well?
