Actor's Colony is/was on 179 Roosevelt Dr. Route 34 Seymour, CT. 06483. Phone (1-800-228-6775) Unfortunately, there was a fire there a while back and I don't know if the restaurant ever reopened. You might be interested in this.....
"Actors Colony sauce takes it's roots in the Marchi Province of Northern Italy. This recipe was brought to America by Desolina Lucarelli who cooked at Actors Colony Inn for almost 30 years before turning over the chef duties in 1977 to her Grandson, Dominick Pirritino, the current Executive Chef and General Manager."
