I just drove up Route 1 north past the Scarboro Marsh, and saw that the former Carson's Family Restaurant, closed now a couple of year (not missed in the slightest) now sports a sign "Bintliff's American Diner" out front, which wasn't there earlier this week.
I called the Portland Street location. They said it's opening this FRIDAY, breakfast lunch and dinner, same brunch menu, breakfast until midnight. Also, this October they'll be opening "Bintliff's Steak House" in the old Natasha's location.
My daughter says she'll go there with friends next Saturday. We should have info for you really soon.
I'm going to like being able to go to Bintliff's for brunch without going into Portland, and without waiting in line, though that situation may not last.
