Armida’s Chicken Parm with White Sauce

When I was at MIT in the 1960s, my go-to places to eat were the F&T Diner, where I sometimes had dinner at six in the morning, and Jennie’s in Boston’s North End, where on Wednesday nights we could get all the spaghetti we could eat for around five bucks. For a night out, though, there was a different choice: Ida’s on Mechanic Street. Calling it a street was generous. It was really an alley overlooking the entrance to the Sumner Tunnel.
