BOLINGBROOK, Ill. (WLS) -- It's not the Golden Arches exactly, but customers are already "loving it."
Hundreds lined up for hours in Bolingbrook Thursday to get a taste of the very first CosMc's in the world.
McDonald's new spin-off restaurant was supposed to have a soft-launch opening Friday in the Chicago suburbs, but eager patrons got early access to some sweet treats.
"We're going to order a lot of stuff," Plainfield resident Chad Lee said.
The Lee family didn't want to miss out on fast food history.
"Let me tell you what happened. Two days ago I got a cousin named Howard, he said, 'Do you see what's coming to Bolingbrook!?' That's all it took," Lee said.
The site near Boughton and Weber roads in Bolingbrook had long lines at the restaurant's four drive-thru lanes.
Employees directed an endless stream of cars with the help of pink stickers.
"It's for individuals who are in line already, because I think there's a lot of people trying to cut.," Romeoville resident Alexis Rocha said.
A spokesperson for the company told ABC7 that they had only planned to serve a small amount of people as a test, but once more people got in line, they decided to serve them as well.
An official opening for the restaurant was initially expected to happen Friday.
The Bolingbrook location is leading the way in the company's roughly 10-city pilot program for the beverage-led, drive-thru only concept by McDonald's.
"It was very, very exciting to be the first, not just in the United States, but in the world," Bolingbrook Mayor Mary Alexander-Basta said.
The company made their official announcement of the restaurant's opening and menu items on Wednesday.
"This was delicious," Lee said.
