NEW YORK — Restaurants are doing away with dining rooms as consumers increasingly order food deliveries through apps such as Uber Technologies’ Uber Eats and GrubHub.

The newest Chopt Creative Salad Co. location, which opened Tuesday in New York, is unlike any of the chain’s other 61 sites. It has no cash registers or tables for customers.

Atlanta-based Chick-fil-A Inc. has similar sites in Nashville and Louisville, where customers order and prepay online with the option for delivery or pickup.

Chick-fil-A is also trying something different, opening three pilot “delivery kitchens” this year — in Chicago, Los Angeles and one near San Francisco that is run by delivery platform DoorDash Inc.

At those sites, the chicken chain shares kitchens with other restaurants to prepare food for delivery only.

Off-premise digital orders are a major growth area for fast-food and fast-casual chains. More are turning to these so-called dark, virtual or ghost kitchens, which can also save labor and real estate costs.

Wendy’s Co. said during its Oct. 11 investor day it aimed to open two “dark kitchens” by year’s end in high-delivery markets. Its franchisee in the Dominican Republic opened one there last month.

A Wendy’s spokeswoman said she could not yet disclose locations for its next dark kitchens.
