Oh boy, do I remember that sandwich! When I was a kid, my family stayed at a bungalow colony called “Taub’s Maple Grove” in South Fallsburg, New York. There was a restaurant called “Barry’s” in South Fallsburg that offered the roast pork on garlic bread sandwich. You could have it with duk sauce on one side and chinese mustard on the other, but I preferred duk sauce on both sides. Yum! Years later, I’d make it myself ordering from both Chinese and Italian take-out places. Haven’t had it in years. – Karen
