The main setting for DoSaB is Prague, which is the capitol of the Czech Republic where goulash is a super common and hearty dish found in pretty much every restaurant and pub. In the novel, the main character Karou and her best friend Zuzana often enjoy goulash at a special hangout called "Poison Kitchen". The café, accessible through an ancient graveyard, was converted from monk's quarters previously attached to a church that burned down some 300 years prior. The story goes that one monk went insane and killed his companions by poisoning their goulash; hence the café's name. It's decorated with real skulls, old statues, coffins as tables, and WWI gas masks. Two years before the novel begins, Karou and Zuzana, both new art students at the time, were asked to paint skeletons on toilets in the bathroom. They were paid in suppers for a month, and were regulars ever since.
"Fine. Okay. I'm dying for some goulash.
Get it? Dying. Ha ha."–Zuzana, Chap. 10, Daughter of Smoke & Bone by Laini Taylor
