What People's Say About Place

Hands down the best diner on LI. I've been going here for decades and the staff always treat you like family. There's a big multi-page laminated spiral bound menu with so many choices. It's the perfect place to go for breakfast, lunch or dinner either by yourself or with a group. My go to is the Deluxe Waffle (hot, golden, crisp yet fluffy waffle with two eggs and your choice of bacon, ham or sausage). Great appetizers, soups, burgers and sandwiches to name a few highlights as well as specials that change regularly. They're always eager to make sure you have a good meal and check about food issues. It's always lively and buzzing, there's a full bar with tv's if you want to grab a drink and have a bite while watching a game. The food is always good and the servers are so friendly and all the staff are attentive. Definitely more than your everyday diner, more like a visiting with family at a restaurant - most days Stella or Peter will greet you with a big smile and escort you to your table. If you want to have a really good diner experience, Nautilus in Massapequa is the best spot.

Visited on the night of August 15, 2025 (a Friday). It was a good night to go out to eat here. I attached pictures of my meal & dessert. I’ll be back again soon. Keep in mind it costs $4.99 extra to replace French fries with onion rings. For dessert lemon meringue & strawberry cheesecake are excellent.

This is a very spacious diner, the appetizers are good and my main course gyro was very tasty. This diner has plenty of parking and is very clean. The wait staff and owner were very professional and attentive, I highly recommend.

Excellent experience three months later roasted chicken, stuffing ,potatoes, broccoli, and enough to eat again tomorrow so much so much fun dessert

This is a great diner still here from when I was a kid growing up in Massapequa. It hasn't changed in the 40 years since I was last here as a teen. The food and service are as good as they were back in the 80's.

Food was very good, atmosphere was great(conversations were had) and service was commendable!!! Very large dining area, good for big parties.

Hands down the best diner on Long Island. Consistently great quality food. Best French toast. Best diner burgers. Pete is the man. Love coming to this place over and over again. It is a staple in the area!

I love coming here the food is always fresh and the presentation on point for a diner. The staffs uniforms are superb makes you feel like you're in a fancy restaurant. I had the soft shell crab franchise so good. I highly recommend it and they have a full bar for those that want a cocktail with dinner.
