Love Jimmy's. Great little place. Small so beware there could be a wait. Only about 4-5 tables plus the bar stool area. Cash only!!!! But food is great and staff are nice. Great little pit stop. Always enjoy going here. read more

First time visiting Jimmy's Dinner. The diner is small and quaint. Friendly staff. Good selection of breakfast items. We ordered pancakes, French toast, eggs, bacon, sausage, hash browns, and coffee. The food was fresh, hot and tasty. Will visit again. read more

Jimmys diner is awesome including staff! The food is great and priced fair! The staff are very nice and welcoming. I will definitely recommend Jimmy's diner. The diner is very small for seating so avoid during peak hours. read more

Im fairly new to the Area as I moved here from Queens this September after buying our first house. Growing up I spent a lot of time in North Carolina and absolutely loved the small diners there with great food and that real family feel. Since September my girlfriend and I had not tried any of the diners out here. I have driven past Jimmy's so many times and never thought to stop in. Today I did and all I have is regret that I hadn't stopped in sooner. The food was excellent and the staff was very polite and friendly. The experience brought me back to those days I loved as a kid in North Carolina. As long as I live here in Manor Park I will be a frequent customer. I highly recommend Jimmy's Diner read more

Amazing food! We went for breakfast and thoroughly enjoyed their home cooking. Friendly service. Highly recommend!!!

Food is always on point. Homemade taste Great service. Only issue is i dont go as often as id like

You can't go wrong with jimmy's Dinner. The food is great. The atmosphere is hometown family. If you like cozy and a family friendly this is the place. Thank you for a good meal and a friendly smile. read more

i'm guessing they have 4.5 stars for not killing people. that's cool. it's basic standard breakfast. so i guess for that i should give a higher rating and yes, french toast can be screwed up but i'm not interested in giving 5 stars for adequate. i was really looking forward to loving this spot and finding a hidden gem in mastic shirley but the service was unfriendly, the counter was sticky, i had to ask a few times for a fork.... for food that was responsibly priced and served hot but i could have made at home and eaten off of a clean surface. with a fork. read more

Great little business. Small and cash only, so be aware! But always great service and good food!!!!

Somebody HAS rated this place already, and that person is John D. (Though regulars peppered the narrow little place on a weekday, I didn't even know this was here til their fairly new signage was erected.) While I'm not sure that it's well-known enough for that to be 'hard to believe', I'm also uncertain that it is as widely reviled as many joints within spitting distance. That's not to say it doesn't have potential to be fulsome on an off day for Jimmy's or a bad day for you, however, as the experience can get a little overwhelming, from the gravel lot to the narrow hear-everything-fellow-patrons-are-saying ambiance. The wind outside whipped everything in Jimmy's all over the place, but it was still kind of endearing in a homey, aunt-Linda-serving-you-breakfast-at-a-counter kinda way. Jimmy's Diner is fairly innocuous, far as diners go, with a inoffensive "decor" and a contrived menu (albeit with all the classics and some solid grub). In the same vein, it's cash only and the wait staff knows 90% of the clientele, yet even newcomers are "honey". Came in for a quick bite ten minutes before closing, yet no one was in a rush to split, as the staff chatted it up with customers instead of bringing me a check. One topic of conversation was the name-unknown-to-them Farm Country Kitchen in Riverhead, a good sign by any means, but the "breeze" took hold of everything else and threw folks off course. My tasty Hank's omelette special with some rye toast set me back $7.55 and came with all things I have at home - tomatoes, baby spinach, & mozzarella cheese - but that's not the point of diners (good ones, at least). read more

I have been coming here since I was a kid. The place is super tiny and is CASH ONLY but the food is AMAZING! Staff is always super friendly and accommodating. Each time I go I order breakfast and I think the portions are huge. Coffee is always fresh. Even when busy it's not too long of a wait for a table. Love Jimmy's! read more

I love Jimmys! fun,friendly atmosphere. Delicious homestyle food. Pancakes are especially fantastic there, so soft and flavorful. I try to get over there about once every two weeks. Price is quite reasonable, and its nice to go to a place where the staff is having fun and treating every customer like family. read more

Lived in mastic Shirley my entire life and somehow at 24 years old this was my first time. It will surely not be my last. Walked in sat down at a table in the back drink order was immediately taken and served quickly. Ordered the omelette with ham peppers and onions with a hash brown and whole wheat toast. 5 minutes tops I had my food and it was delicious. I was the only person in there they didn't know my name. Atmosphere is as friendly as could be and super comfortable. Coffee was great as well. Couldn't ask for more. Highly recommended for a quick easy delicious breakfast. Will be back very soon, maybe even tomorrow. Great job jimmy. read more

without a doubt the best burgers! tiny place that packs out fast- the reason being great food great service and great prices! Breakfast is always great too! This place has been here since I am a kid- they used to open real early, 4 am for the fishermen- i mean back in the day! (and close right after lunch) I remember the original Jimmy... that's how long I've been going there. an Icon of the community, like Skippy's used to be too, I miss Skippy's! but that was a whole different kind of place, across from the drive in movies.... ahhh, old Mastic........ read more

Not from the area, checked on this app. All compliments upheld great service and great comfort good. Will be back again.

Consistency is king. Always friendly, local service accompanied by a simple-'this is what we do' kind of menu. No need to dress up here, just make sure your pants have elastic because its so easy to pig out! This place is abnormally fair priced; and just good old fashioned quality food from your moms kitchen. You MUST try the rueben( greasy & delicious).Working crowd no matter what time of day comes here to eat well and get back to the grind. Jimmy's diner is a quiet gem I hope doesn't change too much! It feels good to spend my money here. read more

Great little greasy spoon hole in the wall place. Make some of the best biscuits and gravy I've had anywhere.

My favorite breakfast spot on LI. Quaint little hole in the wall, but delicious food nonetheless. Sometimes those small little dingy spots have the best food/service. This is one of them. read more

Great service. Very friendly. Tough ha I g a party greater than 4 people. All the patrons extremely friendly. A great local stop with standard good American diner fare. read more

Great breakfast! Great Service! Veggie omelette was delicious as well as the French toast. I'll be back.

Loved this place- food is quick and delicious... asked for my home fries well done- and guess what?!?- they were!!! Most places don't accommodate that. We had and egg sandwich, and hubby had an egg white veggie omelette... very good and quick read more

Quick service...friendly staff....good food. Also the prices are very reasonable. Can get a little busy at times, but definitely worth the wait. Pretty sure it's cash only so keep that in mind. read more

Quick, easy, and tasted like homemade. Service was exceptional, very kind and attentive. French toast was out of this world and bacon was perfectly crispy. read more

Best breakfast anywhere! Pancakes, eggs, Bacon... can't beat the food or the service!

Love it worth ever penny. Fresh hot food cheap. Comforting fills.

I moved to buffalo a Few months ago. I miss this place! Delicious egg sandwiches! I hate eggs and only eat steller sandwiches once in a while. Jimmie opened my eyes. I'm addicted and was a regular. The cooks so nice and would make me mashed potatoes and egg sandwiches as soon as they would open too. I love you guys, all the team that makes it what it is. Super friendly, cheap, hearty sizes. you are the best on li. Super friendly they know what the regulars want always. Can't wait till I visit! read more
