You probably don’t expect to find superlative challah and matzoh ball soup at a Connecticut diner, but here it is at the Blue Colony in Newtown. The Fairfield Daily Voice is running daily profiles all this week of the five diners that are finalists in their reader poll to determine Fairfield County’s best diner. Today’s look at the Blue Colony also praises the Reuben, giant cookies, and Belgian waffles, as well as the attentive, longtime waitstaff. Voting will run through the 25th.
