Back in 2013, New York City’s largest hotel, the Hilton Midtown, discontinued room service to its 2,000 bedrooms, replacing it with a one-size-fits-all café. They weren’t the first or the last to ditch the tradition. Chains across the world from Embassy Suites to Hyatt have been cutting back delivery hours, adding grab-and-go markets, or forgoing room service all together. Even some designer boutique hotels, which theoretically home in on individual customer experience, are reassessing their dining strategies. A hospitality consultant from PricewaterhouseCoopers told Reuters that room service is “a drain on [a hotel’s] ability to perform” due to cost ineffectiveness. (This imbalance is why hotels charge such an astronomical amount for everything on the menu—they are trying to make up for the even more astronomical cost of running a full kitchen all hours of the day.)
