Andas McDonald’s CEO Chris Kempczinski recently revealed, the main focus at CosMc’s is drinks.

As it happens, Bolingbrook is only a short drive from my hometown in Chicago’s northwest suburbs.

I finally reached one of CosMc’s four drive-thru speakers after waiting for about an hour and 45 minutes.

The taste:Very sweet and very weak.

In fact, I barely got any espresso flavor at all in this beverage.

Those who prefer less intense coffee drinks may not have an issue with the milk-to-espresso ratio in this option.

But as someone who likes coffee with the strength of rocket fuel, I found the latte disappointing.

The turmeric flavor was warm and pleasant, but a little too weak for me.

Overall, this option lacked oomph.

It’s also topped with cold foam and toffee sprinkles.

A small one cost me $4.39.

The cold foam had also already been mixed into the cold brew inside the restaurant.

CosMc’s S’mores Cold Brew

The taste:This was unpleasantly acidic from the very first sip.

This was the least enjoyable item by far from the whole taste test.

A small one cost me $4.69.

CosMc’s Popping Pear Slush

The look:Just like something you might sip on at a carnival or state fair as a kid.

The layers of bright pink slush and white whipped cream were very aesthetically pleasing.

On the downside, the drink began separating at the bottom almost immediately after I picked up my order.

CosMc’s Tropical Spiceade

The taste:Way too sweet and lacking enough tartness to balance the overload of sugar.

I haven’t tasted enough prickly pears in my life to say how accurate the flavor was.

It reminded me of an apple-flavored hard candy with a sort of melon-y undertone.

There were also too few popping candies on top to add any sort of actual “popping” effect.

This option reminded me of a melted popsicle, and not a very good one.

The look:By far the most visually pleasing CosMc’s drink I sampled.

There were distinguishable layers of yellow lemonade and that purple-pink dragonfruit floating on top.

I have a feeling that many social media influencers will be drawn to this photogenic, colorful drink.

I really love tropical flavors, so I enjoyed the refreshing combination of lemonade, pineapple, and dragonfruit.

If the sweetness was toned down, I could imagine myself happily sipping a Tropical Spiceade poolside on vacation.

CosMc’s Strawberry & Cookie McFlurry

I went for the Herb Ranch.

The pieces were identical in color, size, and shape, giving them a very manufactured look.

However, I had some major issues with the texture.

They were cold, slightly hard, and tough to bite through.

It cost me $4.99.

The brioche bun was soft, glossy, and perfectly toasted on the inside.

The taste:This is aheavysandwich, but still very tasty and zingy.

It was very subtle at first, but grew a little more with each bite.

I’d rate the spice at about a 4 out of 10.

The sandwich cost me $4.99.

The look:Pretty similar to the Spicy Queso Sandwich, but a little more exciting.

That avocado tomatillo sauce provided a green pop of color to an otherwise beige sandwich.

The bacon looked plentiful and crispy, while the cheese was perfectly melty.

In fact, it’s probably one of the better fast-food breakfast sandwiches I’ve tried in my life.

The bread was soft and buttery.

The cheese was gooey and flavorful.

The bacon was a little thin and floppy, but still had an enjoyable smoky and salty taste.

The true star of the show, however, was that avocado tomatillo sauce.

It was creamy, tangy, vibrant, and elevated every flavor on the sandwich.

It features the vanilla soft serve blended with shortbread cookie crumbles and dried strawberries.

One McFlurry cost me $3.99.

The look:Delightfully pink and chock full of mix-ins.

It was almost like eating strawberry shortcake that had been transformed into a frozen dessert.

Aside from the food, I did enjoy visiting CosMc’s for the novelty alone.
