Best WLM Reviews

We made reservations and had 7 people in total (family and friends). Staff were nice enough to mix 2 tables into one so we can all fit and be comfortable. Took our orders quickly and food didn’t take too long to arrive. Oreo milkshake tasted good, my meal was alright.
Friendly service even at midnight. As a late night Uber driver, it's difficult to find places that are open late just to grab a coffee or to use the facilities and to clean up. This diner is very accommodating. I was tended to promptly and felt special. Clean facilities and clean atmosphere. Highly recommended and will be stopping by for their amazing looking menu
Food is great and the staff is really nice. Generous portions and many traditional diner options. It is very warm almost hot in the building so be prepared to take off a layer if you get hot easily.
Do you know how Atlantis is a lost city under the sea? Well, so was the service here- first we didn’t get menus. I had to go upfront to get them myself. Second, the waitress never came to our table for at least 15 minutes to not even ask if we wanted coffee. Fuggedaboutit….
This was an interesting experience. Kudos to Theresa for serving me and making this review better. The food was very good, and I would eat here again. I must say the waitress assigned to my table never acknowledged me, apologized for making me wait and not serving me, or even checking on me. Theresa, a manager took care of me with great service. If you read this Theresa, thank you!!...
6/16/2023.. I returned to have super and after waiting 30 minutes without being acknowledged I left.
Today we had 14 of us. We are Senior Citizens that graduated from Massapequa high school many years ago and we get together for breakfast, which we do once a month! This was our first time at Atlantis diner and it will not be our last as we will attend our breakfast there every month from now on! Eli, our server was beyond excellent and took care of all 14 of us! He was always there asking if we wanted more coffee and knew what each person ordered! Thank you for Being so attentive to our needs! Even with straws and napkins! A big thank you goes out to Teresa, the manager, who is so accommodating, friendly and welcoming us to share our future Breakfast Gatherings! The food was also terrific!!!!
Sunday evening, Atlantis Diner was the scene of an unsettling incident. Diner had 3 empty 6 person corner booths and the rest of the diner was half empty. A young father wanted to seat his autistic 5 year old in one of the corner booths away from Halloween displays that were scaring the child. He was rudely told NO because the seating was for 6 and his was a party of 3. Father explained child is special needs and needed to be in an area away from Halloween decor to be able to eat comfortably at the diner. Dad was rudely denied the request by the manager. (Halloween decor, in lobby, are animated and typical Halloween grusome.) Dad became highly agitated because he said it is difficult to take his son out.to eat and the half empty diner would have made it possible, away from Halloween decorations. The manager's nasty refusal angered the dad, who overreacted and handled this inappropriately, at having his request for seating to accommodate his son's disability rudely denied with no apologies. The manager at the Atlantis diner could have granted the simple request to allow a special needs child to comfortably eat a meal in peace but chose to discriminate against a child with a disability. The father chose a time when the diner was at less than 50% capacity in an attempt for his child to experience eating out. Child was well behaved. We chose to take our business elsewhere and will no longer patronize this diner.
We went with another couple. Our first time. We ordered from the dinner specials menu. Everyone loved their meals. And we all had enough left over for another meal. Junior (our waiter) was awesome. We’re definitely going back.
PS the desserts are also very good. And they have checkerboard cake
