Buns Up

BunsUp is chef Derrick Foster’s high-end version of the classic fast food slider. The menu takes inspiration from the classic American burger, from Kansas City food culture and from dining experiences as far away as Southwest Asia. The Steakhouse slider, for example, is a classic beef patty topped with classic beef patty topped with A1 mayo and onion jam. The Midwestern, he said, is a “classic cowboy burger” with bacon, cheddar cheese and a popular, locally made barbecue sauce, Blues Hog. The Asian-inspired Green Fire slider is made with pork and topped with a peanut cabbage slaw, green onion and raw jalapeno.

The idea for a slider joint comes from Foster’s memories of a now-closed White Castle fast food restaurant in Overland Park. 

“I used to go there after family events or baseball games,” he said. “Now you have to go to St. Louis or Nashville to get some White Castle.” 

Instead of making that trip, Foster did his own version of sliders, made with local beef and indulgent toppings.
