Honestly, the Breakfast Burger was the BEST burger I’ve had in my 44 years so far. It is a monster, dripping with egg and beef juices. I ordered it medium rare and it was perfection. The fried onion that came with the curly fries was cooked perfectly light and crispy. Definitely my favorite diner in Long Island now.

The food, service, and atmosphere were very welcoming. Elmer, our server was very courteous and knowledgeable of the menu. The daily special dinners are a really good value. The beef stroganoff and chicken tips were prepared perfectly. We will definitely be returning soon!
