Abby was really quick to come take my order. All smiles and friendliness. Great hamburger and o rings. It’s hard to find a really good fast food burger. Try this. The meat is cooked right. Lots of fresh veggies. I have seen this place for years but never tried it. I will be back. Great local eat in your own car dive. Oh and the rootbeer is made right here. Service was fast and genuinely friendly.

If you have not already been to K-N you absolutely should. If homemade Rootbeer isn't enough of a reason how about fresh never frozen cheeseburgers? Crispy onion rings and amazing munchers. You'll thank me later.

Food was delicious. Fries fresh, burgers nice and crisp. Fair styled corndog and fried grilled cheese was amazing! Strawberry shake was perfect and the food was not greasy at all. Definitely coming back again!

Love this place!! Kendra took care of us and she did a wonderful job. Took time to talk to us and get everything we needed. The root beer float was soooo good!!! Definitely my favorite one ever. And I loved the corn dog!

Awesome old school root beer floats. Homemade root beer freezes onto the vanilla ice cream creating a fantastic flavor.

Finally stopped by. It was awesome!! Root Beer was perfect. Cheeseburger and fries like home. My waitress was so personable and has worked for them a long time. Will definitely be back!

This place is fantastic!!! I came here while visiting Amarillo. Everyone says go try Whataburger if you are ever in Texas. Well I gotta say K-N makes a far better burger and fries but you must get the Texas mug root beer to wash it down !!! Excellent spot and I will miss this place A food , root beer and service

Wow! That root bear float hit the spot!! The root bear is really good and it's so cool how it crystallized on the ice cream.
