The Buckhorn is a third-generation family restaurant. It first gained notoriety in 2005 when GQ wrote an article highlighting their green chile cheeseburgers. Then a cookoff with celebrity chef Bobby Flay gave the Buckhorn international attention.

While experiencing success in the industry, Olguin was diagnosed with cancer and his perspective on life changed.

"It was stage three, you know, all the chemo, radiation and everything. So, going through this process, you become a little bit more humble about your life and realize what's important,” Olguin said.

He said now that his colon cancer is in remission, he wants to spend more time with his wife, kids and grandkids.

"We live in a fast-paced life and it's all about competition and money. And the ol' timers always tell you to take the time to smell the roses. There's a lot of meaning to it when you reiterate your life,” Olguin said.

Buckhorn will serve its last burgers on Dec. 12.
