Great location, ample parking, the food is delicious and freshly prepared. The service is prompt and attentive. Great ambiance as well. And the one thing that I absolutely love about having a meal at a diner: being able to hear each other at the table! read more

Heritage Restaurant Diner - Great design! - American Near Me - Mount Sinai, New York

Excellent pancakes and breakfast foods. It is our favorite diner. Service is always great, the outdoor eating area is very nicely done. I don't understand all the negative comments here but I will speak for myself and say 5 stars! read more

Visit Date: June 10, 2025 My two friends agreed to drive out there and meet me for our monthly girls only breakfast. I'm a lunatic, I like running and I like running in different locations. I am trying to run in every single town I have a list in on Long Island. Usually I run after we eat so they supported my crazy and met me here for breakfast so I could do a Mt. Sinai run after breakfast. It's a cute diner, it definitely has the cute aspect down, with canvas photos of different diner nostalgia and diner menu offerings. They have a great outdoor seating area it was too rainy to eat outside or I would have went for eating outside. I got the coffee and I chose the sour dough breadbasket with eggs and jam inside of it. I thought it looked like a unique menu item I couldn't get elsewhere. The bread was good, the eggs were a little bit on the bland side and the jam was good as well. One of my friends is my boyfriend's housemate so I gave her my leftover food to take back home for him. The service was good too, still a three star diner in my opinion based on food but I would come back here again, it wasn't terrible. read more

Heritage Restaurant Diner - American Near Me - Mount Sinai, New York

Service: usually Excellent, friendly, knowledgeable, and will gladly ask if a certain order is available because of the time of the day. Ambiance: Inside: Comfortable, very clean, updated furnishings not overdone. The staff is always making sure everything is clean, and no cluttered tables awaiting cleanup. Outside: Many plants to greet your arrival. Nice to see even if you're not an avid gardener. There is a patio placed off the entrance side, approximately 8 to 10 tables. This last Winter caused a havoc to the wooden planters and definitely needs professional upgrades. It's ok but not my liking to sit on a parking lot on blacktop on a Summer day. Food: Usually diner good, not happy with the additional cost of 3.50$ per cup of coffee when it was included weekdays. Its a 20% tab to the bill, hence reducing the number of days we go there. (as others have mentioned) Bring back the coffee included please and see the volume of patrons come back more frequently). This order was Simply THE worst ever eaten there. The two of us ordered the "Classic Tacos " Being hungry for a taco for a while seemed like a good try. The menu (I think) priced them out for 6$ each, or three for 17$ Anyway..no big savings there..skip the coffee (saved 7$)..who likes coffee with tacos anyway. Well, along came the three tacos each: A small plastic covered container each of: Sour cream Hot sauce Guacamole And three crispy "beef" tacos. The first bite told me..this is not tasty. DRY, dry, dry... Not like I am accustomed to when ordering a beef, crispy taco anyway. A "classic taco " to me is: A Beef hamburger fried put into the shell, topped with shredded montery jack or a mexican mix cheese, tomatoes in small chunks, lettuce chopped, and top it off as you want..usually black olives cut up. This batch had: A small bit of sliced beef with a bit of lettuce next to iis fold, and American, yes, yellow American cheese sliced in small squares sprinkled on top. I really don't know if it had, tomato, I must have, right? LOL. If I made anything like this at home.. I would ditch it. Anyway, after four tacos were consumed, out of an order of six tacos, the 36$ bill was a lesson learned. My error..but remember: "Do it once, lesson learned,Do it twice, blame yourself " Enjoy your day read more

Ordered omelet with toast and potato salad. Waitress pointed out that the wording is "toast and potatoes." Since I ordered potato salad--which by the way was one of the options offered--- I would be charged extra for the toast. I declined. My buddy ordered another omelet minus onions. The omelet shows up with onions, which he picks out. He points this out when she shows back. No apology. No break in bill. She comes back with story from cook on how it may have happened. Huh? read more

Heritage Diner - A Bright Spot for Lunch The eatery is big, bright, clean, and inviting. The menu choices are extensive, offering something for everyone. My wife and I stopped in for lunch and were greeted warmly, then immediately seated at a cozy window booth. Our waitress, Rosalie, was helpful and attentive throughout the meal. I ordered a three-egg omelette with fries and rye toast -- everything was cooked just right. My wife had the BLT on sourdough, which she thoroughly enjoyed. We both left happy and satisfied. The coffee deserves a special mention -- rich, smooth, and excellent. If you enjoyed this review or the photos, feel free to leave a comment! read more

The food quality was average. The service was less than friendly bordering on rudeness. I haven't been back since my initial experience when they first opened. As for the ambience, i would consider it typical of a diner. read more

Clearly there is new ownership. It has been a to go to diner- food & service always good. Met some friends there today- menu a little confusing but decent. They Had the Largest Font promoting Trump Vodka. I asked why his vodka is being promoted and not another brand(ie Tito's ). The guy couldn't really answer, then said "he's the President and he's popular". I told him that was a Mistake- I will no longer support this business. Sad but true. read more

One of the worst meals I ever had in my life. I'm sure breakfast is good but do not go here for dinner or lunch.... This is "chicken and biscuits"- charred/burnt chicken with dry biscuits. My family got a grilled cheese on stale bread, cheese not even melted and a meatloaf sandwich on a stale roll. read more

Came here with my girlfriend, girlfriends sister & her husband for a late night dinner. Loved the dinner feel this place has and made me feel like I was at a local dinner back in queens. Staff and waitresses were amazing and the atmosphere here is great. Very family oriented and local spots for family breakfasts, lunch, and dinners. Came here and got a burger and it was one of the best burgers I got in a long time. My girlfriends sister recommended the burgers and she was right. The burgers here are top tier and I highly recommend. Great milk shakes as well and just had a solid dinner here. If your looking for a great dinner in Mount Sinai, don't look far. This place is awesome and they have great diner food. read more

My family and I have eaten there literally dozens of times, and our most recent visit was the last one for sure. After seating the 3 of us, we waited for a few minutes for the server to come take our drink order (which she did). We ordered our meals which amounted to a couple bowls of soup and 2 burger platters. it took 20 minutes for the soup and then after an additional 20 minutes we were advised by the server that the kitchen "got slammed" and that the food would be a little while longer as a result. I advised her that we needed to be at a wake and that if the food was going to be more than a couple minutes longer, we'd have to cancel the order. She brought over the check for the soups and soft drinks, and I went to pay and while doing so the manager brought over the burgers which were wrong, one was supposed to be regular without cheese. I let the manager know that we'd been there for 45 minutes and at this point we had to go and that the service wasn't acceptable. No offer of an apology, nothing... poor customer service is inexcusable. With diners being closed all over L.I. you'd expect better service from one that's been there as long as they have. Disappointing to say the least. read more

Impressive service! It was my first time here and we were greeted by a man in a suit with menus in his hands and seated us as soon as we opened the doors. It's like he saw us coming up the ramp or something. That was awesome. We got a nice server. Very sweet girl. Can't forget her...she had a blue bow in her hair and matching blue eyeshadow lol. She took our orders pretty fast, and food came out just as fast. Our orders were pretty simple: - eggs scrambled with american cheese and home fries and rye toast - steak & eggs w home fries and toast - coffee The food was enjoyable. We didn't plan on coming here, but glad we changed it up this day. I will be coming back to try other things on their menu read more

Heritage Restaurant Diner - Fresh Strawberry French Toast - American Near Me - Mount Sinai, New York

Is this diner under new ownership now? We live in Ridge. It used to be very good and we'd trek past Rocky Point diner to go to Heritage. My beef gyro was comprised of processed thin almost see-through strips of meat like you'd find in a super market freezer section; arrived without tzatziki sauce, and was overall a poor attempt of a sandwich, with a very pathetic side salad. My lady ordered a tuna melt, which was served open on a pita with neon yellow fake looking cheese, and luke warm fries at best. Come on man! I guess now we have to drive further west to Lake Grove diner. read more

What a phenomenal dining experience we had yesterday. The menu was extraordinary with such an array of different food selections and drink choices. Our server Sam and the rest of the staff were so friendly. The food portions were incredible and the prices were very fair. read more

I try not to leave negative reviews, but tonight's experience earned it, and I was generous with 2 stars. A Monday evening, not busy. No pictures, as I didn't expect to make another review. Our dinners came with soup and/or salad to start, and usually they come out right away (it seemed like a long wait) Instead the server chose to bring them out with our appetizer, which we ordered the choose your own sampler platter. As everything was brought to the table, she drops the entire tray. Okay, stuff happens, she is apologetic and we sympathize. Another wait. The Greek salad, standard, can't really mess that up. The French Onion soup tasted like salty water. The appetizer sampler platter: baked clams were a soggy, bread crumb, flavorless mixture. Clam strips burned beyond being edible, chicken fingers were fine, as was the spanokopeta bites. My dinner was the steak teriyaki, a small portion, but edible, nothing spectacular. My husband had the parmagiana trio: chicken, shrimp and eggplant. Terrible! The chicken was tough and stringy, the eggplant was burned and the shrimp was burned on the outside and a chewy mess on the inside. The only sauce the spaghetti underneath had, was whatever dripped off the trio on top. The check arrives, with no mention of a discount for the dropped appetizer inconvenience or even an offer of a complimentary dessert. We are not the "Karens" to ask or demand, but that was disappointing customer service. The overall experience was enough to keep us from returning. read more

Finally! A decent diner in Port Jefferson. My kids had a sleepover and about 11:00pm I surprised everyone and said lets go to the diner! Its funny how teenagers try to be all cool when ordering. I know my son wants a sloppy hamburger with onion rings. One of the kids ordered a chicken wrap and then the other kids ordered the same thing. Me and my ten year old ordered french toast which they always make to perfection. I wont succumb to peer pressure dang nabit! Great burgers, breakfast is always great, I'm a fan! read more

Waitress was rude, did not write anything down, got the order wrong. Found a hair on the pickle that came with my burger which was burned.
