I went to the Seaport Diner in Port Jefferson , NY. Service was horrible, the waiter takes 25 minutes after sitting down to come over and take our drink order then another 20 mins just to take our dinner order. Finally about 40 minutes after ordering we get our food. We ordered Salads that should have came out before our food did. We got our food then had to remind the Waiter about the Salad and which Salad we got. That took another 20 minutes. To put the cheery on top of everything, I order a burger and fries. The fries were good ~ burger not great at all. When I go to eat my burger I noticed that the plate that my food was served on was not cleaned and it still had old food from the person before me who used this Plate. I noticed the Waiter after waiting 25 minutes for him to come ou

We came for dinner and had the steak and shrimp—everything was cooked perfectly and full of flavor! The drinks were great, and the milkshakes were the perfect sweet treat to end the meal. The atmosphere is cozy, the service is top-notch, and the food is consistently amazing. Whether it’s brunch or dinner, Seaport Diner is always a great choice!
