The Bottomless Cup by Kevin Boehm
Bottomless Cup is like a real-life version of the TV show The Bear. Kevin is a kid from a dysfunctional family in Michgan who decides he wants to get into the restaurant business. He starts with a tiny beachside cafe in Florida and ends up as co-owner of the successful Chicago restaurant group Boka. In between he finds and loses love, has a family he knows he's not spending enough time with, drinks too much, has resounding business success--only to come face to face with an industry shutdown during the pandemic, and comes close to committing suicide. I was glad to see that he had finally gotten his life on a more even keel by the end of the story.
