He's very happy. Best falafel in the Midwest (did a tour and charted every recipe, then created his own).
Keeps his crew for years - the normal term is months, especially in a college town. He's brought his management experience from Engineering teams to food prep and cooks and servers, some of who've never been treated like professionals and peers in their lives.
Does catering too, and supplies restaurants with 'snack packs' which are very popular around here.
I enjoyed working in restaurants in my formative years but I don't think I'd be happy owning one. Honestly I think my dream job would be working on a cargo ship or something but sadly I'm well past the age cap for breaking into the field.
