Neptune Diner Syosset

Just visited the new Neptune Diner in Syosset and had a great experience. The service was excellent, the staff was super friendly, and the ambiance was warm and welcoming. We went as a family, and the kids were happy with their meals—grilled cheese and chicken fingers from the kids' menu. I tried the tenders too, and they were really soft and flavorful. I ordered the chicken kebab platter, swapped the rice for home fries—great choice. The chicken was juicy and well-seasoned, and the lemon mustard sauce added a nice kick. The grilled veggies were done just right. My dad had the house-made turkey burger and really enjoyed it. Neptune Diner is a great addition to Syosset—family-friendly, tasty food, and a relaxed vibe. We'll definitely be back!

Prompt service. Generous portion size. Lots of options in the menu. Reasonably priced breakfast options. The place is VERY CLEAN. Plenty of parking.

I always go to this dinner. I love you guys and all, but when people put their DoorDash order, I live like five minutes near you guys and I always come there all the time but when you guys get your online orders because I have like four kids so I can’t really get out sometimes too Get my order, but please don’t forget the people that do their orders like DoorDash because I feel like the food is not as good when we put it through DoorDash as it is when I come there in person and I get it cause I’m gonna come there a lot because the food is very delicious but please care about the DoorDash orders like you do like the people that come in regularly because I’m noticing a difference in the taste from when I come in Versus my DoorDash orders thank you. Have a great day. Because you guys 100% mes

Busy Sunday morning diner crowd, excellent service, great food! There was a wait around noon this Sunday, they moved people in quickly,.high chairs for the kids, the restaurant was sparkling and clean, food was hot and delicious! Everyone enjoyed the meal. Loaded pancakes with Nutella and bananas were so good I couldn't get a picture before they were almost gone!

Went for the first time since this diner became Neptune the other night. Got a burger deluxe. Ordered it medium. It came well done, but was still good nonetheless. The staff was friendly, but not the most attentive. Overall the food was good. They renovated the inside, which looks nice, and clean. The food does seem to be on the pricier side. All on all, I'd go back.
