State Line Diner has been family owned and operated for over 35 years. Located in Mahwah, New Jersey, the reason behind our continued success is our usage of high quality ingredients in our vast menu …
First, I'm SO happy they offer turkey for their Open Grilled Reuben !! The French Fries Side Order is a generous portion, which they include ketchup for (small detail, but when you live out of a hotel is so appreciated!) It was a nice consideration that they put the dressing on the side, and they provide enough for the full sandwich. definite 10 out of 10!

Virginia Ham Steak and Eggs The steak is HUGE and delicious.
California Avocado Toast was ok but FYI it doesn't come with egg even though it's listed under "Eggs"on the menu.
Short Stack were fluffy and yummy! I got them with fresh strawberries which were also yummy and in their own container so nothing got soggy.

Used to love this diner. For years! Past few omelettes have been raw with liquid egg in the middle. Unacceptable. My burger bun was hard and super stale. They've also mixed up fry orders and forgot items, including the typical Cole slaw and pickles that used to come with every order. Hope they return to form soon, for all our sakes!

Absolutely horrible. The food was so undercooked, poorly packaged and leaking everywhere. I paid over $100 and the quality was atrocious. The sauces didnt have lids on them at all which lead to every package being covered in salsa and sour cream. The Cheesburger Deluxee was so undercooked it was practically raw. The Grilled Amer. Cheese Sandwichdidnt even have melted cheese but the bread was burnt. The shrimp Quesadillas were barely cooked at all....cheese wasn't melted and it was very sloppily thrown together the salsa and sour cream were slammed into the package. The French Fries Side Order was so undercooked that you couldn't eat them. I had to throw it all out.
Save your money and dont order from here at all.
