Food was decent and the service was great. My group of 5 had the breakfast and 1 fish sandwich. Everyone left happy and full. It’s popular place so be wary of wait times , even at midnight/1am

20-30 minute wait to be seated on weekends. Food comes out fast though. Staff are very friendly. The food is decent. I ordered eggs and bacon but received sausage. I was starving and after that long wait to be seated I didn't want to make a big deal out of it... Nonetheless it's Worth paying them a visit!

I decided to have an early dinner with a friend who suggested this place. We arrived around 5:30 and were seated immediately. I ordered some apps with a half-n-half, and my friend ordered the Lumberjack breakfast with an Iced Coffee. Our waiter and the staff were terrific. The restaurant was packed with great energy and a friendly buzz from couples and family groups. I love the vibe of this diner situated between Bed-Stuy and Crown Heights❣️

I really wanted to like this place, but the food just didn't deliver. The burger was bland and completely tasteless - honestly, the mushrooms I added had more flavor than the beef itself.<br><br>The fries were fine, but very average for a diner. Nothing bad, nothing memorable - just standard fare. The onion rings, however, were a miss. They were soggy and completely saturated with grease, like they'd been sitting in a vat of cold fryer oil instead of being freshly made.<br><br>The real disappointment was the carrot cake. Calling it carrot cake feels generous. It tasted like a generic supermarket cake with basic icing - the kind you'd grab for a kid's 3rd birthday. No cream cheese frosting at all, which is kind of the whole point.<br><br>Not terrible across the board, but definitely not something I'd go out of my way for. A lot of room for improvement.

I love this place the ambience, the food, the location, but one thing that is unpleasant every single time I’ve gone is the sound. I wish I could understand why they think people want to be blasted with loud obnoxious music the entire time they’re eating and hanging out. I can only surmise that they’re trying to encourage people to not hang around too long. Even if the music was more to my liking, it’s just too damn loud.

I definitely recommend it. They cook the best meat in all of Brooklyn here, absolutely delicious no matter what time you feel like coming. Everything is super delicious, and the staff is very friendly and helpful. Very pleasant, and the prices are good. 👍😋

I really enjoyed how I was welcomed as I enter the diner. I also wasn't sure about the wine and was allowed to sample two kinds. Jerry is very pleasant, patient and accommodating. He made sure everything was up to par. The food is delicious! Kudos to the chef. You can order anything on the menu at anytime of the day. I will be returning to try something new.

Highlight is the outdoor seating & they’re open 24-hours! Great affordable diner food in the heart of NYC, quick walk from Prospect Park & not far from trains. Staff were attentive & the food was great. Those pancakes were HUGE, giving Big New York energy! There are booths inside and they have a pretty robust menu.

Classic American Diner with a 6-page menu. They got everything from breakfast to dinner and everything in between. The place is very cozy for a quality time with family/friends. Nice outdoor patio as well.

The absolute best diner I’ve been to in New York! I love to come here late night after a party but it’s also great in the daytime for breakfast lunch or dinner! It’s such a classic old school vibe with a great ambiance for dining indoors or on the patio. The portions are massive and it’s a great value for your money. I usually get a sandwich but last time I had this bbq chicken salad which was delicious. Such a solid spot with great service

After hanging out it was 3:30 am and we were looking for a diner that was open. So here I am... My food was delicious 😋. I had corn beef hash with scrambled eggs with cheddar cheese. White toast and a hot tea. We had a tasty turkey sausage as well.

Had a late breakfast after a night partying. We were waited on by William, who was accommodating and pleasant. We had french toast, omelettes, and coffee. It was your typical diner food; it helped us sober up a little bit.

I’m a native New Yorker who came back to the city. Been around and seen many diners. Here’s what’s important to me and why this place is a 5 star review ( we also returned 3 days in a row, party of 8 and they somehow always made room for us.<br>Clean, friendly, fresh and 24hrs!<br>Breakfast, lunch, and just ask for what you want, they’ll make it for you!

My family and I had a great time here! The food was absolutely perfect! Prices were great. I had a burger with fries and chicken tenders with honey mustard. It was all wonderful. My wife had eggs, bacon and French toast. I tried the French toast and it was amazing!!!! I couldn't stop eating it. Service was friendly and super fast. Bathroom was clean and smelled great. Employees were cleaning the dining room and chairs. Music was good. Couldn't ask for more from a diner. I will definitely be coming back very soon!!
