Absolutely the best diner food I've ever eaten. The potato salad was delicious. The Cole slaw was incredible and the Reuben sandwich was the best Reuben I've ever had and I've had many. I live in Hauppauge, so I usually dine at the hauppauge diner but I will travel a little further from now on for sure!
