K-N Root Beer Drive-In Amarillo

K-N Root Beer Drive-In Amarillo

Share

One of Texas' oldest drive-in restaurants. The only restaurant in Amarillo to get homemade root beer.

There’s a reason the Patty Melt has been a diner legend for generations.

Fresh never frozen ground chuck smashed on the grill, buttery grilled onions, melted cheese, and thick-cut Mrs. Baird’s Texas toast grilled until golden brown. Simple food done right just hits different.

And if you know… you know it’s even better with an order of munchers and our housemade ranch on the side.

Some combos never go out of style.

Nothing to see here… just some deep fried Uncrustables casually changing lives at KN Root Beer.

Hot peanut butter and jelly wrapped in golden fried dough, dusted with powdered sugar, and somehow tasting exactly like being 10 years old again… except way better.

Crispy outside. Gooey middle. Absolute problem.

And fair warning… once one hits the table everybody suddenly wants “just one bite.”

We probably should’ve kept these to ourselves.

This is why we do what we do. ❤️

We got the sweetest letter from a student named Ethan from Kerrville, Texas asking about our root beer… so of course we had to write him back 🥹✉️

Moments like this remind us that KN Root Beer isn’t just about drinks—it’s about history, tradition, and sharing something special from one generation to the next.

Keeping the Knutson tradition alive, one root beer at a time. 🥤

Ethan, if you ever make it to Amarillo… your root beer is on us. 💛
