While it seems like this place has had a poor history of service, I have to admit that I had a pretty great time here. The interior is well furnished and clean, and the lox eggs benedict I got was great -- eggs were poached just right, and their hollandaise was flavorful without being too strong. The home fries and milkshake that accompanied were also prepared just right for my tastes. No hairs to be found anywhere!! Service was prompt and friendly, so all in all I didn't find anything to critique. I would definitely stop by again if in the area. read more

I frequent the "millennium diner every Friday night and I am so happy that my favorite waitress "Jovanna" is back. Excellent waitress, excellent service and just a joy. If you attend after 5:P.M. ask for her!!, You won't be disappointed! read more

Decided to give millennium a try on my way to work. The waiter indeed had no idea about the menu, but he was attentive to refills and gave me updates on my order without me asking. Food was average- I ordered the eggs benedict and it wasn't terrible or mind blowing. Wished it was cooked a little bit more because it still had raw white in it. Overall, mediocre diner. Would rate as 2.5 read more

Went later in the night and the lady was obviously tired and couldn't care less about the last fee customers and was pretty careless when it came to our table. Food was alright. Not the best I've had. read more

I'm sorry, but I don't get all the bad reviews. It's a diner. We had two complete dinner specials, and they were both quite tasty and portions were enormous. We have enough for at least a whole extra meal. And the flavors were good. Very heavy, but that's what you expect at a diner. Huge dessert selection, as well, which didn't disappoint. And very friendly service on top! Great experience. If I lived closer, I'd definitely be back. read more

This diner is by far the best I have been to in a while. Staff treats you like family. Food is excellent. Large portions and desserts to die for. A must for chicken noodle soup and cole slaw. Head down to enjoy a great meal read more

This place is a complete dump. Not even sure how they are still in business. I usually go to stony took or the hauppauge diner but we were right there and kids were hungry. Should have known when it was completely empty at 6pm on a Saturday night. Had the French onion soup - bland no taste. Potato skins had melted American cheese on top?!!?? Are u kidding me? I thought it was a joke. Then the turkey club wrap had the most dry turkey I have ever had. EVER. Absolutely terrible. I have never written a review. This is my first. But I just had to, this place is terrible. read more

We ate an early dinner last night at the millennium around 5:30. The place was very busy so we were seated immediately. There was some obvious confusion by the wait staff as to who's table we were seated at so we waited a short time for the children to work it out. When our order was taken our food arrived quickly and correctly. Portions were a good size and the food was tasty. No complaints there. The place could use a face lift, it was clean but a little dated. It may be time for the "new millennium". read more

Stick to basics like burgers and omelets. I had a truly terrible piece of chocolate cream pie here. It was one of the worst things I've ever tried to eat. Smelled like diesel fumes and was stale. read more

Tried the pineapple chicken and I was extremely pleased my wife had the chicken cordon blue and I sampled some...wow great food great service would definitely recommend read more

Great Jack Daniel's salmon highly recommend always satisfied there and the homemade desserts are to die for...thanks for the great food service and atmosphere read more

Had dinner at Smithtown Millenium Diner last on 8/16/19 at 8pm. Food was a crime against the senses. Steak tips, teriyaki. The rice was bathing in sauce loke a soup. The veggies were way overcooked and cut too large. The soup was like a paste with the contents limp and uninteresting. Stuffed clam in aluminum shell was awful and the dessert was stale and not edible. Assuming it is pre-made from a bakery, they managed to ruin that too. The mens room looked like an e-bola experiment. Neighborhood and customers deserve much better. Worst experience ever. Ripped off. read more

Best Diner! Friendly staff and delicious food. I would recommend to anyone looking for a great meal in the Smithtown area.

I'm being generous giving it a 2-Star. Food would be one star. They weren't rude, but definitely weren't friendly. Place needs renovating. Backup to food... I read poor reviews on here before we went, but the people we were meeting suggested it. Since I had low expectations, I told my husband "I'll get an omelette. It's hard to screw up an omelette,". Well, they did. That was the worst omelette I've ever had - not kidding. There was no cheese in it at all. It was a Western Omelette, so I wasn't expecting a gooey mess, but what kind of omelette doesn't have any cheese? That's not an omelette. That scrambled eggs with peppers hammered down into a dried-up, overpriced mess. The potato fries were mushy. My husband did not like his either. Two people had waffles. They were dry and looked very unappealing. Definitely will not return. read more

I'm not sure why there are such low reviews for the Millennium Diner. I've been coming here for years when I head back to Long Island to visit for a weekend and I've never had an issue with the food or the service. In fact, since I find that this is a superior diner, I've come back. Anyway, I usually order some sort of breakfast food at the Millennium, either late at night or during a normal breakfast hour. I enjoy their western omelet and their home fries, so that's my usual go-to meal when I dine here. Certainly check out the Millennium Diner. read more

I have been here several times and the service is hit or miss. However, the last time we visited, after waiting 45 min for eggs, we had to walk out. Others seated before us received their food so I'm not sure what the issue was but after bad service multiple times, and then this experience, we won't be back! read more

Great service waitress was personable and nice I ordered a Greek salad with grilled chicken the chicken was so good and the salad very fresh! It's my third time going there and as always is a good experience my bf ordered chicken parm and the sauce and chicken were both delicious their layer cake was good too the place was busy I would recommend it :) read more

Excellent food and service. Breakfasts are top notch. Owner is friendly and always around. If you are going to give negative reviews to a Diner for decor and parking lot then you have to find better things to do- we always enjoy this place. read more

Great food- Large portions Waitress was very pleasant Decor is beautiful Cashier was very attentive to my special needs read more

Great food with very reasonable prices. I've dined here several times for breakfast and have had nothing but pleasant experiences. The staff is very courteous and the food never disappoints. I suffer from stomach issues but this staff is always more than willing to accommodate my needs. I highly recommend dining here for breakfast....or any meal any time of the day! read more

The absolute WORST diner I have ever eaten in! Don't bother. When I told the waitress the food tasted terrible she said "she didn't think the manager would adjust the bill - sorry." The manager DID give us a break (kudos to him) but I would never go back. Deer park Diner is much better. read more

I like this diner! I had lunch there Friday, and ordered a Philly Cheesesteak - with well-done bacon added on top. Delicious! Also had well-done waffle fries - excellent. Great waitress, nice people. And the cheesecake is also really good! read more

Food was Horrible, chicken very dry , bread burnt. When told about their bad food I was told it was excellent. Threw up half hour later. Do not eat here. read more

Service was inexcusably slow - After lunch time and not very crowded. Food was all disappointing: soup was tepid, panini not pressed or hot, tuna salad was more mayo than tuna, milk shake was thin, wings were not good and $16! Can't even make decent toast . read more

Wow, finally a Diner with great food an extensive menu and top notch service!! I started with the french onion soup and I was very pleased. The broth was perfect just enough swiss cheese and the rest just melted in your mouth. For my main course I chose the broiled stuff sole. Now I have had this over and over at other diners and everytime it was a let down. It was either over cooked or flooded with butter. At Millennium it was very good, the sole was cooked perfect and I ate every last bite. Ok, I can't lie I took a piece of there Baklava home for a late night snack and boy o boy did that hit the spot. A++++++ read more

We visited Millennium Diner in Smithtown 2 nights in a row. The first night we had desert & it was very good. The second evening we dined with another couple & had dinner. The dinner was exceptional, very well prepared, & lots of it (we had to take it home). Our waitress, Laura, was very helpful in suggesting what was available. She was professional, pleasant & friendly. She even laughed at our silly jokes. She was easy going & always available for anything we needed. We will definitely return to Millennium very soon. read more

Have been going here for a few years and it has been in decline for a while. Last ordered Yankee Pot Roast, and while eating the potato pancake noticed something black in the it. Called one of the owners over and he took it into the kitchen and returned and said it was spices (parsley?). I didn't believe him and opened the whole thing up and it had a large area of black. This could have been mold or who knows what else. Spoke to him again and was told the same thing. This was our last visit. Fortunately I spotted this before I ate it. If they can't serve fresh food what am I paying for??? read more

Stay away! TWICE I've eaten here and both times there was a black hair in my food! Once in the home fries and once stuck in the butter on my toast. Absolutely disgusting. read more

I know it's just a diner, but it was the worst experience we've ever had at a diner. Saturday afternoon 2:45 NOT busy at all. We ordered a cheeseburger deluxe, bacon cheese omelette and a grilled cheese with tomato and bacon. It took 35 minutes before our order came and when we asked the waitress what happened she said she put the order in and when she went back to check on it, the guys/cooks had not started cooking it. When we asked for the owner, he didn't have the balls to come and apologize. He sent the manager to let us know that the grill cheese would be on the house. It's not about the money you jerk, it's about the service...WORST CUSTOMER SERVICE!!! It was the first and will be the last time we ever go there. read more

OMG The most disgusting food you could ever imagine. And not cheap either. Should be against the law to expect payment for their slop

Where do I even Begin... I ordered a dinner that came with everything, Appetizer, Soup or salad, Steak,veggie, potato, glass of wine and desert... How bad could a simple plain steak be? Boy was I wrong...The appetizer was ok, the soup was horrible, (that should have been my first indication the meal was going to bad), the bread the waiter brought to the table was stale. As far as my main meal, my Steak was not only cold, but from the first bite something just didn't taste right so I took a sip of my soda to cleanse my mouth and tried it again, still it had that bad odd taste..... I had both my husband and sister try a piece only to figure out that It was old meat...I was so grossed out and nauseous... Called the waiter over and explained the problem, I told him that I didn't want it... He spoke to the manager and came back and asked me if I would like something else, (Really I'm not eating another thing from this place I said to myself), to which I responded no thank you and he said are you sure because we are still going to charge you for the steak because its an expensive piece of meat so you might as well get something else.... I was enraged, (REALLY after serving me bad old meat I'm still going to pay for this)? No mgr came over, no apology was given, my food wasn't taken off the bill, mind you it was barely touched and none of the sides were eaten.... We barely made it home, I live 5 min's. away, and ran into the bathroom sick as a dog!!! Sick all night and the majority of the next day... Finally at 5:45 PM the next day I was able to eat some crackers and drink some warm ginger ale...I think The Board of Health needs to pay a visit to The Millennium Diner We definitely won't be returning to this place!!!! read more

Just went for lunch and i dont think i have ever had the worst meal. The coffee was burnt. Water was not refilled once. Waitress only checked in once. Fries not cooked all the way through. The avocado was gray, tomato one step away from rotten and the capers were so overcooked it almost broke my tooth. Im speaking of the Chipolte Panini. My husband ordered bagel all the way. He had to ASK for the onions and olives as they were not on plate, and when they were, it was WHITE onion. Tomatoes were horrible, the peppers dry. The hostess was friendly and the nicest part of the place. Waitress seemed distracted and i felt like i was bothering her when i asked for extra napkins. WOULD NOT RECOMMMEND nor will we go back in the future. read more

There are quite a few choices for breakfast in Smithtown, all good, but Millennium Diner is our favorite. They cook eggs perfectly, their hash browns are spectacular, the coffee is great, and the service staff is very fast, and so thoughtful and friendly. All in all, our favorite diner. read more

Just horrible horrible horrible !!!! DO NOT GO HERE !!! Not only did my waitress tell me that my finances burger was a "bison burger deluxe" but she told me that it was just a "really big burger" she then brought out a burger that looked exactly like mine ( I got the twin cheeseburger deluxe) we all know the bison burger is a slightly larger and meatier burger than the norm here and this lady was in the effing clouds!!! When it came time to pay she charged us $4 extra for a meal I didn't get !! Ugh anyway after tellin her that we were not happy the manager asked us "did he eat the burger?" Umm yeah he did !!! You told him it was the bison burger !!! Of corse he's gonna eat what he ordered and especially after we had the waitress tell us that in fact yes this is the bison burger she charged me for a twin bison burger deluxe!! So I finally pay the bill and left no tip for her ... After reviewing my account online I saw that they put a $4 tip on my card!!!!!! I went back to the diner to confront the manager (who was an old Greek man who could barely speak English) told me that that's not possible what we put on the recipes was what we put the bill thru for ... So I said "what makes you think that the waitress and the "manager" on duty that night didn't add to the bill when they were settling the bills that night??" He replied " no cuz it would say it on the receipt" UM NOOOO IT WOULDNT !!! They are shady people !!! And I will never ever ever go here ever again !!! I blew you up on Facebook and now I know that this will be seen by people !!! ABSOLUTELY HORRIBLE read more

Excellent service waitress was very friendly and on her game I ordered the French toast stuffed with cannoli cream it was huge I ate half and was stuffed. It was delicious but it was pretty sweet. Will definitely be returning here to try some of the other options read more

The Millennium Diner is a "can't miss" if you are passing through or live in the Smithtown area. The food is excellent and the service is always with a smile! I've been dining at the Millennium for years and I never leave disappointed! I especially love the Greek Salad and fabulous lunch and dinner specials! I recommend to all!! read more

I have been to this diner many times and enjoyed each time! The food is fantastic, better than most diners I've been to. The service is also very good and everyone is very friendly. Definitely recommend it! read more

Panini made with day old stale hamburger rolls. Staff could care less. We won't be going back.

When you're in the mood for a diner, you mainly want simple food, this place is it. A month or two ago, I went to a different diner and ended up getting a smoothie and a few other things. Now at this diner, they don't make smoothies, so if you want a smoothie, I would suggest going to a different place. The food was fairly good but the main problem was the service. I have gone here plenty of the times, and most of the time the service was good. This time when I went the service was okay, but very annoying. We asked for some honey mustard, and the server just looked like us like "what do you want?" and I was very upset about the service. So if you want a good place to eat, I would suggest a different place! read more

I've eaten here many times and have always enjoyed everything from salads, sandwiches, to burgers and entrees. The place is always clean and the staff is courteous and professional. read more
