    DON'T Listen to the bad reviews! You will miss out on great food. This is my fourth time coming here and every time we come we get great food and great service! This last time was exceptional. Our waiter Elvis was extremely attentive and accommodating. He made great recommendations that helped us all to order exactly what we wanted. We ordered things that weren't even on the menu (trifongo - Mofongo with plantains, Yucca and Maduros). When he heard that me and my friend were going to split the trifongo and the Cuban sandwich, he had the kitchen split our plates for us with no extra charge. All of us loved our meals, not a single complaint. If you haven't eaten here yet, Peconic Diner is a must try!

    Brute and open , not your typical diner !

    So I had no intent on making a review ! In my head I was stopping for a quick lunch ordered one of my fav.. Cubano. I aimlessly requested well done fries and an additional soda. I ate without registering anything g but it was one of the finest Cubano ever, wish I had taken some photos, but if you know , you know. Newly renovated and a Caribbean flare to its menu, the Peconic diner is reborn with plenary of space, a great vibe and young staff eager for greatness. It's a great stop offering a large menu, the new diner experience.

    The Peconic Bay Diner/Latin Bistro, depending on if you read the signage out front or the menu inside was ok. The new renovation is a little strange. One room is Diner meets sports bar and another room has a cocktail lounge vibe. Maybe that will pull in a new crowd that wants an all in one experience but all I need is a good diner. The food came out quickly and my order was correct but once I got my meal I had'nt had a visit until the check came and that was about 15 minutes after I was done eating. I really like a refill on my coffee in that type of restaurant but didn't get one. The pancakes & eggs were good but the bacon was definitely not made fresh and probably pull out of one of those stainless bins in the refrigerator. The price was fair especially compared to IHOP but it doesn't have the same cozy old school diner vibe as it did before. I probably won't be making another visit here unless I feel like giving them another chance down the road.

    Fried Chipotle Chicken Sandwich

    I have always gone to this diner after going to the Riverhead outlets. I was surprised to see the name had changed so I was skeptical about going in. I had the chipotle fried chicken sandwich and as you can see the chicken was 1. Not fried but a patty? Which was barely cooked and hard. I took 2 bites and physically could not eat the rest it was absolutely disgusting. 2. There was not even chipotle mayo on it. My boyfriend got the classic cheeseburger and took one bite and could not physically eat the rest because he said the meat didn't taste like beef. The french fries were cold but we were so hungry we ate them. The waitress never came to check on us after ordering so we could not tell her how awful the food was. She put us in a corner away from everyone even though it was not busy. I would not even give the leftover food to my dog. None the less we paid for our meal but we would never come back here. I am extremely disappointed. The restaurant was very clean and everyone was fairly nice but the food was horrendous. Nothing like the diner that was there beforehand. I would not recommend this establishment.

    Not like a diner. Menu not nearly extensive as a diner. Service was pleasant and fine. In short not what I had expected.

    I had previously stopped by Greek Island Diner to pick up soup for a sick friend, and after that…read moreexperience, we decided to come back for an early Friday dinner. Wow, we were seriously impressed. Parking was easy with plenty of space, the diner itself was spotless, and the interior was bright and welcoming. The staff was friendly from the moment we walked in, and we were seated right away with no wait. Edgar took care of us and was fantastic. He was super friendly, attentive, and genuinely welcoming (and yes, "took care of us" feels more accurate than "waited on us"). We started with two soups: beef barley and lentil. Both were absolutely delicious, comforting, flavorful, and clearly made with care. Of course, I had to try the mozzarella sticks, and they did not disappoint. Perfectly cooked, and the marinara sauce was thick, tasty, and not watery at all. For our entrees, we ordered the Philly cheesesteak melt and a beef/gyro panini. The portions were generous, and the flavor was even better than expected. Even when we were full halfway through, we still wanted to keep eating because they were just that good. We couldn't leave without dessert after walking past the display on the way in which showed so many options. We went with the chocolate layer cake, and holy moly. The slice was massive (looked like half a cake) and absolutely amazing. We couldn't finish it, probably should've skipped the fries , but it was hands down one of the best cakes we've had in a long time. Overall, an excellent diner experience from start to finish. We'll definitely be back and will likely become regulars. It's that good.
