My wife and I just spent a few days in Bar Harbor, and our best meal was on the way back home. Just Barb's is a small unpretentious restaurant on Rt 1 in Stockton Springs, between Belfast and Ellsworth. I got fish & chips (all you can eat for 4.99). The fries were generic, but the fish was absolutely wonderful--small 1-inch square pieces fried perfectly. My wife got fish chowder, and she said it was some of the best she's ever had. Lots of fish, excellent non-thickened broth. The waitress said each serving is made to order. Also on the menu--fried tripe! Definitely worth a detour if you live nearby or are passing through the area.
