McDonald’s has announced the details of its new restaurant idea, CosMc’s, which would operate in the same market segment as Starbucks.

Its pilot will open this month in a part of Chicago, with a plan to be in about 10 locations by the end of 2024.

Meanwhile, the fast-food giant also plans to open about 10,000 McDonald’s restaurants globally by 2027, with many of those in China.

The expansion would boost the number of stores to about 50,000.

The first CosMc’s is due to open in Bolingbrook, Illinois later this week, with about 10 more to open in Texas in 2024.

It will serve a menu that seems to be squarely aimed at people with a very sweet tooth, selling items such as Churro Frappe – churros are a kind of Spanish doughnut – and S’Mores Cold Brew – s’mores are biscuits, chocolate and marshmallows.

There will also be a cut-down list of McDonald’s staples on the menu such as Egg McMuffins.

It already has a coffee and snack chain called McCafe, which only serves coffee and sweets.

The name for the new brand comes from a McDonaldland mascot, an alien from outer space that craves its food, which appeared in adverts in the late 1980s and early 1990s.
