I often visit the Ellsworth area (a town between Bangor and Bar Harbor) and until now hadn't found a comfortable cafe to really hang out in and work- which is my fave thing to do.
On Main Street the Maine Grind has coffee from Rockland roasters, free wireless, great food including a bagel with locally smoked salmon from the owner's other business, and great coffee.
It's a really comfortable place. My sister lives in the area and I'm glad we discovered it so she can get the word out like wildfire.
So if you're passing through and need a break, turn right on Maine and you'll see it.
