Their menu truLy goes over and beyond ;ingredients variety of items items that are absolutely savory delicious and something you would want to run back to 🍽️ 🏃♂️ !!
I really have nothing bad to say about this place, and I’m still giving it 5 stars overall. The food and service have always been great. But guys… these are not onion rings 😂. They’re way too small and honestly just not very good. When you go to a diner, you expect big, regular-sized, crispy, juicy onion rings — the ... kind you actually look forward to ordering. I really hope the owner or manager sees this because this is an easy thing to improve. Please bring back some real onion rings! Read More
I’m very lucky I live very close to Seaport diner here in Port Jefferson. The food is spectacular. The people that manage this diner are wonderful people. Kind and giving and helpful. I can’t even praise the food enough because I go there at least twice a week and every time I am there, I try something else that’s ... remarkable. No doubt this is the best diner anywhere near where I live and I recommended highly. I had a dish there called salmon Aruba that was absolutely incredible. I highly recommend that if you like salmon. I am a grateful client no doubt.⭐️⭐️⭐️⭐️⭐️ Read More
We stopped at Seaport Diner in Elizabeth, NJ while staying near Newark Airport and absolutely loved it! The food was delicious, fresh, and plentiful, the prices were very reasonable, and the service was wonderful. ❤️ It has that cozy, old-fashioned diner feel that you just don’t get everywhere anymore. Nothing fancy, ... just really good food, generous portions, and friendly people. Exactly what we were looking for! If you’re staying near Newark Airport or just passing through Elizabeth, definitely give this little gem a try. We would absolutely eat here again! 🥞🍳☕️ 5 stars from these Pennsylvania travelers! ⭐⭐⭐⭐⭐ Read More
Great great diner, if you want to step back in time and go to a diner with great food, large portions, and super friendly service this is the place. Also the onion soup is legendary. Don't pass this place by a real gem of a diner.
Great
Well worth the trip over to the Seaport diner
What can I say that hasn't been already said? Seaport Diner serves some of the best tasting meals on the Island. My cheese burger deluxe came with New Jersey sourced beef steak tomato slices the size of dinner plates! Cheddar cheese, and a nice Brioche bun and onion rings made fresh...oh and a mountain of French ... fries...it reminded me of the old back in the day Pioneer Restaurant in Hauppauge. Excellent staff, minimal wait to order and wide seating choices (we were in a horse shoe booth) really made our visit there so much more.. An Excellent value for your money. Read More
