Halloween doesn't have to mean takeout between trick-or-treating rounds. A private chef dinner turns the evening into an actual occasion, a playful, multi-course Italian meal at home, before or after the costumes come out.
Menus can lean playful and seasonal, or stay completely classic if that's more your style, it's entirely up to you and your guests. I've cooked Halloween dinners for adult get-togethers and for families winding down after trick-or-treating alike.
Halloween falls on a weeknight some years and a weekend others, and dates around it get booked quickly either way. If you have a date in mind, I'd reach out with a few weeks' notice.
