In our opinion Three Sisters will appeal to certain people and not to others. Some will like it's laid back, small town, dinette atmosphere. Nothing fancy, good food, large portions. Others will also enjoy the good food but will be displeased with the lack of space, mismatched dinning wear, less than average coffee, barely toasted toast and the "greasy spoon" environment of the building.
Some will see 4 or five stars, go there and say "dead on. Loved the place." Others will wonder how someone gave them more than three.
We went back and didn't enjoy our food as much as we did the last time and the coffee was not very good. Also we thought the prices were higher.
Anyway, love it or leave it, it is a three star restaurant in our book.
