Feb 10, 2021 Shane Dunlap/Pittsburgh Tribune-Review via AP Valley Dairy general manager Alex Blystone prepares a taco order at Valley Dairy Restaurant, Thursday, Jan. 28, in Latrobe, Pa., as part of their new ghost kitchen business, Taco Joeâs. LATROBE, Pa. (AP) — For those who believe, ghosts come in a wide variety of forms: floating orbs of light, haunting voices or, as in the opinion of famed fictional ghostbuster Raymond Stantz, “a full-torso, free-floating apparition.” As it turns out, so do “ghost kitchens”: food-world phantoms that put emphasis on flavor rather than fright. A ghost kitchen, or virtual restaurant, uses an existing business to create a new menu available almost exclusively through delivery, and frequently through third-party delivery services such as DoorDash, GrubHub, Postmates, Seamless and Uber Eats.
