CosMc from McDonald's
CosMc is back.
  • McDonald's is expanding restaurants and testing new designs around the world.
  • The chain announced plans to build a spinoff restaurant called CosMc's.
  • The restaurant is named after a McDonaldland character named CosMc, the company told Insider. 

McDonald's is opening a spinoff concept called CosMc's, CEO Chris Kempczinski told investors Thursday.

"Our new business ventures team is in the process of developing a new concept we will call CosMc's, which we will test in a small handful of sites in a limited geography beginning early next year," Kempczinski said during the chain's second-quarter earnings call. "CosMc's is a small-format concept with all the DNA of McDonald's but its own unique personality."

The CEO said the company will provide more details on the concept during its investor day at the end of the year.
