A downtown pop-up dinner this month was both a collaboration between two local chefs and a return to the spotlight for one of them — Gina Marinelli. About 50 people attended the recent dinner, “One Night, Two Chefs, Three Courses, Fo(u)r a Good Cause,” which paired Marinelli with Justin Kingsley Hall, executive chef at The Kitchen at Atomic and was a fundraiser for the nonprofit Urban Seed Foundation.

Pop-up dinners such as this, where guest chefs cook in someone else’s kitchen, have become common in Las Vegas’ close-knit culinary community. An appearance by Marinelli, however, has been anything but commonplace for the better part of a year, since the closure of D.O.C.G. at The Cosmopolitan of Las Vegas last summer.
