Once Costco members are done browsing the store, they'll often make a last stop at the food court. This department even features one item that Costco sells more of than any other retailer.

Costco’s food court is famous for its Kirkland Signature all-beef hot dog, and the chain sells more hot dogs than any other retailer, about 151 million a year. This popularity is likely because Costco has kept its hot dog combo meal at a cool $1.50, despite inflation.

Costco used to use Hebrew National franks as opposed to Kirkland Signature, but the switch was eventually made to keep costs down. Costco co-founder Jim Sinegal has been very adamant that the combo remains at its low price, reportedly telling CEO W. Craig Jelinek, "If you raise the effing hot dog, I will kill you."
