Despite their newfound popularity, food critics agree almost universally that concrete milkshakes taste terrible.

Concrete milkshakes have become popular at protests, including among Antifa groups. However, food critics have said they don’t come anywhere near classic flavors like vanilla, chocolate or strawberry.

“I don’t know what the appeal is,” one popular food critic told the Hamster. “Honestly tastes like sidewalk.”

“This makes Antifa even more disgusting,” said another. “Not even sure there is any ice cream in these.”

If they are going to continue being featured at protests, food critics hope maybe they will add more flavors, or at least whipped cream or nuts.
