A Locals Guide: 11 Best Cafes in Chicago
"I mentioned Butterdough in my post about places to eat in Chicago, but I’m listing it again because their coffee is excellent. One of their most popular options is the Cafe con Leche with their homemade cafe de olla syrup. I recommend getting it with regular milk, not their oat milk because the oat didn’t work with this drink at all."
