★★★★★ 5.0 Help Long Island Addiction · Mar 2026

I recently visited hauppauge Palace Diner in Hauppauge and had a solid experience overall. The diner has a classic Long Island feel with a large menu that covers breakfast, lunch, and dinner options. I ordered Eggs and Bacon with Pancakes from which came out quickly and the portion size was generous. The food tasted fresh and the service was attentive without feeling rushed. The restaurant itself was clean and well-maintained, and the staff were friendly throughout the visit. Parking was easy and the location is convenient if you’re in the Smithtown area. Prices were about what you’d expect for a Long Island diner. Overall, it’s a reliable spot if you’re looking for a traditional diner experience with plenty of menu choices.

I had a wonderful experience at Hauppauge Palace Diner with my family! We came in as a party of eight, with people arriving at different times, and the staff couldn’t have been more accommodating. They welcomed the first two of us right away and seated us comfortably, then seamlessly integrated the rest of our group when they arrived 20-30 minutes later. No hassle, no attitude—just warm, genuine hospitality. The food was excellent. I highly recommend the beef goulash, which was absolutely delicious, and the French toast bites were a hit at our table as well. You can tell this is a family-owned establishment that truly cares about their customers. The service was attentive and friendly throughout our meal. If you’re looking for a diner with great food, welcoming staff, and the flexibility

Went here for the first time a few weeks ago. Had the tuna sandwich on whole wheat toast. The tuna is absolutely delicious. Best tuna on the island. Hands down! Had their fries too and they were cooked perfectly and well done. Just how I like them. Went there a week later and had the grilled cheese and fries with mozzarella cheese. It was cooked perfectly once again!! I live in Bohemia but it’s worth the trip. Can’t wait to go back!

This is one of the best diners I’ve ever been to, and the experience is always amazing. The quality of their food is exceptional, and they have a handpicked team of amazing waiters and waitresses. Alexis and the management here are amazing!!! They check in on you and ask how your food is, which is something I’ve never seen in a diner. If you haven’t been here yet, you absolutely must go!

Come here all the time! Great breakfast and lunch, with so many different options! By far the best chicken noodle soup I’ve ever had. Very modern inside and always clean.
