CosMc's menu: McDonald's spinoff restaurant announces grand opening date, menu items

CosMc's in Bolingbrook is officially open to the public!

Mayor Mary Alexander-Basta announced it on social media and said the restaurant will have an official grand opening celebration on Saturday and Sunday from 10 a.m. to 2 p.m.

Normal business hours will be 6 a.m. until 8 p.m. and it will be drive-thru only.

The lines were long on Thursday, with many patrons waiting two hours or more!

"Having driven through the window today, once you get there you get overwhelmed because there are so many options and so many additions," said Bolingbrook Mayor Mary Alexander-Basta.

On Wednesday, McDonald's released part of the new restaurant's menu, which includes "otherworldly beverage creations" such as the Churro Frappé, S'mores Cold Brew, and Sour Cherry Energy Burst.

It almost seems like CosMc's is dipping into the Starbucks market with these types of drinks.

"CosMc’s menu is rooted in beverage exploration, with bold and unexpected flavor combinations, vibrant colors and functional boosts," McDonald's posted on its website. "Make it yours with customizations at every turn: popping boba, flavor syrups, energy or Vitamin C shots, and so much more."

As for its food offerings, CosMc's is whipping up a Creamy Avocado Tomatillo Sandwich and a Spicy Queso Sandwich. It will also have pretzel bites and hash brown bites that come with dipping sauces.

When it comes to dessert, the restaurant will offer McPops, which look like a mini sugar donut stuffed with either apple cinnamon, hazelnut, or cookie butter.

Customers can also delve into a caramel fudge brownie, cookies (sea salt chocolate chip or blueberry lemon), a caramel fudge brownie sundae, and a twist cone! Yes, both chocolate and vanilla ice cream included.

In addition, CosMc's will have some McDonald's classics on its menu – like Egg McMuffin sandwiches and the M&M's and Oreo McFlurry.

The new restaurant is the first of its kind in the US and is located near the intersection of Boughton and Weber roads in Bolingbrook. McDonald's says more locations will open in 2024.

CosMc is an alien creature that last appeared in McDonald's advertising more than 30 years ago. Now, he's finally making his return.
