Good lunch. French Onion soup on the salty side. Tuna melt very tasty! Happy waitress barely any cheese. High prices for diner food IMO.

WOW this place blew me away today. As someone who has lived in nyc for a long time before moving to the area this was the best food I have had in 3 years. The service was great felt very welcomed clean environment very calm. I had the Phillipsburg omelet with homefries and I added peppers and onions so delicious that’s gonna be my go to when I return. I’m gonna tell everyone I know to come try it. Whoever the chef is back there they know what they are doing. Food also came out fast. I love the the waitress actually let you take your time and eat didn’t feel rushed at all. I highly recommend you try this place out 10/10!!!!!!!!!!!!!

They open up strictly at 7:00 a.m. the food was delicious everything was good. I have absolutely no complaints. The diner was on fire a few years ago and it burned down and they rebuilt it and did an entire restoration. The bathrooms are nice and clean as well. There’s scrapple is good as well. It tastes almost like corned beef hash.

This place has been here since 1955 and was going down until it closed after a fire and refurbished the diner. It is much better than ever. The new owners also run the Nazareth Diner which is a top notch location. Key City has quick table service, friendly servers in fact seems they hire only the best. It is a very clean place. Generous portions of food. I notice many people walking out with boxes. Great choices on the menu but I am a fan of their breakfast specials. You can’t go wrong here and will be coming back.

Visited 11/19/25. Great cheesecake, delivered from a local bakery; they are celebrating 25 years so they are offering free coffee from now until the 25th! #TheDinerDiner

Good old-fashioned Diner breakfast but with a price tag! To be fair, I got an egg, white omelette and a bowl of fruit instead of toast, but be prepared to fork cup a little extra cash than expected!

Renovation is excellent. It’s better than expected inside. I grew up with the classic metal diner, I even remember the music boost the tables. That’s all gone, replaced by very well built, clean and modern interior. The classic 1950s was very worn out, and impossible to replace so this new look is where they went.
Portions were generous and tasty. Food quality is high. It’s definitely priced above fast food, but below fine dining. I’m glad I came back and will visit again.

Key City Diner has been here for years and is well known for their great food and quick service. This is always a favorite place to stop for a meal when in the area. The diner is always very neat, clean and well-organized. The owners are very friendly and welcoming – which keeps me coming back. Their wait staff is top notch – it seems they only hire the best. They offer a very extensive menu. Their food is consistently good and they serve large portions. I have eaten here on numerous occasions and really like their breakfast meals. Key City Diner is easily accessible off Route 22 and they offer a large, free parking lot for their customers. Stop here anytime of the day or night and I guarantee you that you will have a fabulous meal. I highly recommend this diner!

The food was good but hopefully they step up their service. I went it was kind of empty and our food took 30 minutes to come out. Even my daughter’s Ceasars salad which is supposed to be quick came al.ist all out with entree 30 minutes after ordering. The host could have been friendlier not that he was rude but I always expect the host since they are the first person you see to set the atmosphere. He was just like how many. Instead of hi how are you have u been here before.
