The CTA Holiday Train started from humble beginnings. Then a holiday celebrity and his helpers turned it into a Chicago tradition.

Chicago is a city of pubs and taverns with a robust drinking culture. During the holiday season, that might mean sipping on some warm Swedish glögg, or, as we heard in our last episode, grabbing a Tom and Jerry at Miller’s Pub. But what about a Chicago-specific cocktail?

“People really want us to have a cocktail,” said Liz Garibay, executive director of the Beer Culture Center. “It's like, you go to New Orleans and there's a Sazerac. You go to New York, there's Manhattan.”

So is there a quintessential Chicago cocktail? Curious City host Erin Allen talks to Garibay as well as Greg Shutters, owner of Cohassett Punch Liqueur to see what they think. Garibay says either way, the city’s drinking culture is shaped by its immigrant and working class roots.

We talk with Garibay and Shutters about Chicago’s drinking scene, past and present.

The Tom & Jerry cocktail didn’t originate in Chicago, but this cakey drink feels very Midwestern. We get into the drunken history of this classic drink, and why it’s become a holiday tradition.

If you’ve ever shown up to a bar on a Sunday afternoon or listened to a concert at the Chicago Symphony Orchestra, you’ve experienced firsthand the lasting impact of German culture in the city.

Last episode, we went to Christkindlmarket, one of the most prominent examples of German culture in Chicago. There are key organizations like the Goethe Institute and DANK Haus. But there are also more subtle, everyday activities we participate in that would be different had German immigrants never settled in this area, centuries ago.

Curious City host Erin Allen talks to two experts on German language and culture. They discuss how it has shaped Chicago’s history and present, from the products we consume to the rights and freedoms we enjoy.

A Curious City listener collects Christkindlmarket mugs. But there’s one mug in her collection without a year on it. We go in search of that lost year.

A curious listener asked why he saw an aviary at O'Hare Airport. It turns out, it isn't an aviary at all — it’s a trap for an invasive species of bird.

Airplanes aren’t the only ones flying around at the airport. Birds often get stuck inside the terminal, and they can be a challenge to get out.

November is National Native American Heritage Month, a time to celebrate and recognize the history, culture and contributions of Indigenous people in our country. If you look around Chicago, you see echoes of Native American history in names like Washtenaw, Skokie and Wabash. But Indigenous history is often presented from a settler or non-Native perspective.

Today, we get into a project out of the Newberry Library called “Indigenous Chicago.” Through art, education and collaboration, its goal is to change the dominant narratives about Chicago’s history with the overarching message: Chicago is, and always has been, a Native place. It all began a few years ago with conversations within the Native community.

“One of the things we heard over and over again was this issue of invisibility,” said Rose Miron, director of the D’Arcy McNickle Center for American Indian and Indigenous Studies. “Native community members found that there were far too many people who didn’t understand the long history of Chicago as an Indigenous place, but also didn’t realize that there was a large contemporary community here today.”

“Indigenous Chicago” is a collaboration between representatives of tribal nations and includes multimedia art, oral histories, public programs, educational curriculum and an exhibition. Curious City’s Erin Allen spoke with curators Miron and Analú María López, the Ayer Librarian and assistant curator of American Indian and Indigenous Studies.

Chicago histories usually start in 1830, but Native Americans were already settled in the region long before that. Curious City fills you in on what some history books are missing.

When you think of a family business, one of two images probably comes to mind: either the mom and pop shop around the corner or the dysfunctional family from “Succession.” But actually, “it could be anything,” says Jennifer M. Pendergast, family enterprise consultant and professor at Northwestern University’s Kellogg School of Management.

Last episode, we looked into the oldest family business in Chicago. And this got us thinking about family enterprise in general: Why do family members end up in business together? What happens when they do? Should they?

Curious City’s Erin Allen sat down with Pendergast to talk about this, plus why she says family business is the “backbone of the economy.”
