Great food. The breakfast is out of this world. Dinner specials are super. The left side rear is where it’s quite cozy to sit.

Been to this diner several times and the food is not consistent. One time it's good and this latest visit was a disaster. The food was not good, the desserts were stale and it was a total disappointment.

We're here.... probably weekly for breakfast (or occasionally lunch). In my opinion the best local diner around. Definitely better than Seaport! The best pancakes!!!! Can get busy on the weekends!

Pretty typical Long Island Diner. Good was pretty decent, service is good. I just think that the prices are a little higher than usual, it could just just cause of thr area. I recommend the pastrami panini.
