If you’ve been scrolling through TikTok or driving around the Chicago suburbs lately, you’ve probably seen the purple glow. It’s hard to miss. Everyone’s calling it the "Mc Cosmic menu," but the sign on the building actually says CosMc’s. It’s McDonald’s weird, caffeinated, slightly chaotic younger sibling that decided to open a drink-focused outpost because, honestly, the world probably didn't need another burger joint, but it definitely wanted more sugar.
McDonald's CEO Chris Kempczinski basically admitted during an investor day that this wasn't just a random experiment. They saw a "white space" in the afternoon. You know that 3:00 PM slump where you’re too tired to work but too awake to nap? That’s where CosMc's lives. It’s a direct shot at Starbucks and Dutch Bros, focusing on "beverage exploration" rather than just flipping patties.
The first location landed in Bolingbrook, Illinois, back in late 2023. Since then, it’s expanded into Texas, hitting spots like Dallas and San Antonio. It’s weird seeing a McDonald’s brand that doesn’t sell a Big Mac, but that's exactly the point.
Why the CosMc's Menu Is So Different
The core of the menu is built on customizability. If you go to a standard McDonald’s and ask for three different pumps of syrup and a shot of energy in your Sprite, the person behind the counter might look at you like you’ve lost it. At CosMc’s, that’s the whole business model.
They’ve leaned heavily into the "galactic" theme. You’ll see things like "Signature Galactic Boosts" which are essentially high-octane energy drinks disguised as fruity refreshments. Then there are the "Cloud Spics" and "Slushes." It feels more like a chemistry lab than a fast-food drive-thru.
Most people are showing up for the Sour Cherry Energy Burst. It’s bright. It’s aggressive. It has these little boba-like pearls that pop in your mouth. Is it healthy? Probably not. Is it exactly what a Gen Z commuter wants on a Tuesday? Absolutely.
The Drinks That Everyone Is Talking About
Let’s get into the specifics of what’s actually on the menu because it’s a lot to digest. The Churro Frappé is a standout. Think of a blended coffee drink but topped with whipped cream and actual churro sprinkles. It’s thick. You’ll need a wide straw.
Then there’s the Turmeric Spiced Latte. This was a bit of a curveball for a McDonald’s brand. It’s earthy and warm, far removed from the syrupy sweetness of a McFlurry. It shows they’re trying to capture that "wellness-adjacent" crowd that still wants the convenience of a drive-thru.

One of the weirdest—and surprisingly popular—items is the Popping Pear Slush. It’s green. It’s cold. It has those zingy popping boba pearls. It tastes like a liquified Jolly Rancher but with a caffeine kick that'll keep you humming for three hours.
Refreshers and Teas
If you aren't into the heavy cream or the slushy textures, they have a massive lineup of teas.
- The Blueberry Ginger Cooler is actually quite refreshing.
- The Island Pick-Me-Up Punch uses a lemonade base.
- You can add "Prebiotic Shots" or "Vitamin C Shots" to almost anything.
It's a customization level we haven't seen from the Golden Arches before. You can swap out milk for oat milk, add extra shots of espresso, or throw in some dried dragonfruit. It feels premium, but the pricing stays relatively competitive with the big coffee chains.
The Food: Small Bites Only
Don't go there expecting a Quarter Pounder. You’ll be disappointed. The food menu is strictly "snacks."
The Spicy Queso Sandwich is the heavy hitter here. It’s got a kick. It’s served on a brioche bun with a fluffy egg, sausage, and a distinct spicy queso sauce that has a bit of a smoky finish. It’s better than the standard Egg McMuffin, mostly because the bread feels fresher.
Then there are the McPops. These are tiny, filled donuts. They come in flavors like Cookie Butter, Apple Cinnamon, and Hazelnut. They’re basically designed to be eaten with one hand while you drive. They are dangerously easy to finish in about thirty seconds.
Surprisingly, they kept some classics. You can still get a McFlurry or a standard fudge sundae. They also have "Hash Brown Bites," which are just the standard McDonald’s hash browns but shrunk down into pop-able circles. It’s a smart move—everyone loves the hash browns, but eating a full rectangular one while trying to sip a latte is a recipe for crumbs everywhere.

The Strategy Behind the Galactic Theme
Why the retro-alien vibe? CosMc was an obscure character from the McDonaldland advertisements in the late 80s and early 90s. He was a six-armed alien who visited Earth to trade space items for McDonald’s food. It’s a deep-cut nostalgia play.
By reviving this character, McDonald’s is leaning into that "kidulting" trend. It appeals to Millennials who remember the weird commercials but also feels "aesthetic" enough for TikTok-driven Gen Z. The branding is all purples, blues, and yellows—colors that pop on a smartphone screen.
Business-wise, it’s brilliant. Drink margins are significantly higher than food margins. You don’t need a massive kitchen with fryers and grills to run a CosMc’s. You need blenders, espresso machines, and syrup pumps. This allows for a smaller footprint, meaning they can squeeze these into tight urban spaces or small corners of parking lots where a full-sized McDonald’s wouldn't fit.
What to Expect at the Drive-Thru
The experience is a bit different. It’s almost entirely digital. You pull up to a large screen, browse the massive menu, and order. There isn't much "window talk." It’s designed for speed.
They also use a "multi-lane" system that’s supposed to be more efficient. If your drink is ready, you get bumped to a specific window to pick it up, rather than everyone waiting in one single line behind the person who decided to order twelve different customized lattes.
Is It Worth the Hype?
Honestly? It depends on what you like. If you’re a coffee purist who wants a single-origin pour-over, stay away. This is sugar-forward, high-energy, colorful fun. It’s the "treat culture" manifested in a cup.
The S’mores Cold Brew is a perfect example. It’s sweet, but it has that distinct marshmallow toasted flavor that actually works. It doesn't taste like "fast food coffee." It tastes like a dessert that happens to have caffeine in it.

The biggest limitation right now is availability. With only a handful of locations in Illinois and Texas, most of the country is just watching it happen on social media. But McDonald’s has hinted that if these pilot locations continue to see the massive lines they’ve had so far, we could see hundreds of these popping up over the next few years.
Actionable Tips for Your First Visit
If you find yourself near a CosMc's, don't just wing it. The menu is overwhelming.
Order ahead on the app. The lines can be brutal, especially on weekends or during that 3 PM rush. Using the app lets you see all the customization options without the pressure of a car behind you honking.
Try the Creamy Avocado Tomatillo Sandwich. It sounds weird for a McDonald's brand, but it's one of the best savory items they offer. It’s got a brightness to it that cuts through the heavy, sweet drinks.
Mix your textures. If you get a slush, add the popping boba. If you get a latte, try the McPops on the side. The whole point of the "Mc Cosmic menu" is the variety of textures and flavors that you can't get at the regular drive-thru.
Watch the caffeine content. Some of those Galactic Boosts pack a serious punch. If you're sensitive to stimulants, maybe stick to the decaf teas or the fruit slushes without the added "energy" shots.
The brand is clearly evolving. They are already testing new seasonal items and tweaking the layout of the Texas stores based on what they learned in Illinois. It's a rare move for a company as massive as McDonald's to act like a scrappy startup, but that's exactly what CosMc's feels like. It’s colorful, it’s fast, and it’s unapologetically focused on the "afternoon pick-me-up."
