After finding out about this diner on social media I finally made the trip out and it was definitely worth every mile! I think this may be my new favorite diner of all time the huge menu was great and the food was absolutely outstanding! Had an amazing matza ball soup along with one of the best beef goulash I’ve ever had. The breakfast eggs were cooked perfectly homefries were perfect as well as the bacon and they had chicken gyro! Usually diners have solvoki but the gyro was amazing and their taziki was on point! I will definitely be making the drive out here again to try more menu items especially the chicken cutlet tacos!

It's a diner which sells a lot of food. Well the choice we made was spot on. We did the pasta tacos 10 out of 10. The 3 tables near us all you can hear was oh my god this is delicious try this. So we will be going back. Oh and to top it off we went on a Saturday night around 6ish and it was packed and people were eating and leaving with very minimal wait. Good job.

I recently tried the chicken cutlet tacos with fettuccine Alfredo here, and it was a surprisingly delicious combination. The chicken cutlet tacos were crispy and flavorful, while the creamy fettuccine Alfredo on top paired perfectly. The portion was generous enough to cover both lunch and dinner, which made the price feel very reasonable for what you get. The atmosphere inside the diner was calm and relaxing, which made it easy to enjoy the meal. Service was generally quick, which I appreciated, but I did have a slightly awkward moment when a server came by to clear dishes. I asked for the check, and they just mumbled something under their breath and walked past, which felt a bit off-putting. Thankfully, my original server was attentive and got me settled without any issue.

After seeing their new dishes on social media we had to try them, and they did not disappoint. The Buffalo Mac and Cheese Chicken Cutlet Tacos were amazing. The chicken taco was delicious. We also tried the Bang Bang Chicken Cones which were just as tasty.

What can I say about this incredible find? EVERYTHING! This is no ordinary diner by any means - don't walk... RUN here! Right off the bat, the staff is friendly, smiling, and attentive. The menu is massive, so you indecisive people should get a head start before you go! Some appetizer hints - go with the Jack Daniel's sliders... beyond delish burgers with a tasty bite. Quality short rib meat blend, and yummy frazzled onions, Everything on the combo platter is home made- nothing frozen. Wings, fried, mozzarella sticks, Mac & cheese bites and chicken fingers. Almost all the sauces are made in-house too. You can literally taste the difference in the chicken fingers - not frozen and made fresh! The marinara is tasty and the honey mustard is BOSS.. Wings are crispy, moist and flavorful, the shi
