YAKIMA, Wash. – Flightline Convenience Center serves up typical convenience store products, but has also become a destination for customers craving Asian cuisine, the Yakima Herald reports. Owners Tae Soo and Hye Jeong Choi added teriyaki and other dishes eight years ago to increase sales—a strategy which has paid off for the couple. Hye Jeong, who was a chef in South Korea, put her kitchen skills to good use in developing the dishes.

In-store foodservice at convenience stores grabbed 20.8% of sales in 2015, according to NACS State of the Industry data. At the Flightline Convenience Center, foodservice sales garner around 40% of overall sales.

As more retailers have moved to offering candy, gasoline and soft drinks, convenience stores have supplemented with fresh prepared foods. TV shows such as “Diners, Drive-Ins and Dives” on the Food Network have piqued interest in food found in untraditional locations, such as gasoline stations. “That can play in the convenience store’s favor,” said Jeff Lenard, NACS vice president strategic industry initiatives.

Flightline Convenience Center also tapped into another foodservice trend by making freshness a top priority. Hye Jeong Choi shops each day for the ingredients to make her Asian dishes. “She wants everything fresh,” said her daughter, Jihye Choi. But the Chois also realize that convenience store food must be affordable. The most expensive dish tops out at $7.99.
