After living here lo, these many years, I believe I've reached the ranks of
The Insider Group.
Especially in the "Good, inexpensive, tasty-food, restaurants" department.
Portland, Maine is truly blessed with more good, gooderer and best restaurants than anyplace I've ever been to – other than my hometown. Even Boston can't compare.
Money issues aside, there's just so many times that you want to don a jacket, wear a tie (not that you need to in many restaurants), but if your dropping the big bucks, you should at least dress for the occasion.
Fortunately, Portland also has a plethora of fabulous restaurants that lack pretensions, require nothing more than your presence and a good appetite.
