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

We arrived late at our hotel and the manager suggested this diner for late dinner. The staff was friendly and attentive and the food really good. I had the angel hair pasta with shrimp and garlic butter sauce and my wife the chicken franchese. We both had green salads that were very generous in size and very fresh. I have... More

We had breakfast here while visiting for a baseball tournament. The food was very good. The service was ok, our waitress didn't seem very attentive. It's a big place so we didn't have to wait for a table which was nice.

The Palace is like an extension of your dining room. The staff is incredibly friendly. Large portions of high quality ingredients makes this a really great dinner. Can't say enough about this place.

I've lived in Hauppauge my whole life and this diner has always felt like "home" to me. As a college kid, I look forward to coming back to town and eating here. Whether it's a night out with my family, catching up with my friends, or taking my boyfriend out, this is the absolute best place. I've come here for... More
