Good service friendly staff clean diner food. The proportions are huge there's always enough for another meal. I would suggest 2 adults can easily share a meal. I'm not sure there's a charge for sharing but it's worth it. We go there often and have always enjoyed the experience whether it's breakfast lunch dinner or a midnight snack after a... More

Been going here since I was a kid. Huge menu and soooo good. Very good lunch specials too. Service is great. Nice big salads. It's a little pricey but comparable to other diners of the same quality.

We just moved to the area a couple of days ago and discovered this place as it is close to our hotel. Due to it's proximity to the hotel (and the terrible weather), we have been twice. The food was good and the portions are huge! The prices are reasonable for what you get. Yesterday, I had a chicken avocado... More

I took 8 happy women after a wedding shower in age from 70 - 15 in the midst of a snowstorm with only 6 other people in the diner and to a person they complained about the horrible service from our surly male waiter. It took forever to have him take our order and the get our food with simple... More

Our server was prompt but the kitchen seemed a little slow for a weekday lunch. Our portions were huge and generally good. Prices are good for the items included.

I arrived late to Long Island and was pleased to find this diner still open on weeknights until 2 am and 24 hours on Friday and Saturday. The Challah French toast was great! Plus I had sausage and eggs. Great coffee and service with the décor of an old fashioned train car diner. Will definitely go back.

First I want to start off saying that the staff was very friendly. The best part was that I have a gluten allergy and they had great options to choose from. And Jerry our waiter was so knowledgeable on what I could eat. He even made sure they cooked my fries in a separate fryer. I can't wait to eat... More

I'm hitting it lucky with, once more, a great diner. I had eggs with the works and it was not pricey. Flap jacks and sausages. Every thing was on point to include the service.

Always busy but never a wait. The food is fresh and always delicious. The wait staff are all friendly. The hamburgers are proper hamburgers and filling, a true meal, accompanied with French fries and onion rings it's a meal you can't find fault in. Pancakes light and fluffy so yummy. Grill cheese are perfection. I have never been disappointed

Went for dinner and made a good choice. The menu is extensive with every kind of food you could want. My wife and I both had their hot turkey dinner. It comes with soup, salad, two veggies,stuffing, and desert. More food than you can possibly eat at one time. The turkey is fresh and not supermarket quality. Our server was... More
