At lunchtime on 3 November 2023, more than a dozen people were waiting outside a popular sundae-guk restaurant in Seoul’s Dongjak District. On-site reporting described two ways to join the same admission order: entering details on a waiting device at the restaurant or registering remotely through an app. A visible line of people and an invisible list stored in the system overlapped at one doorway.
Unlike a conventional queue that requires everyone to remain in place, registered customers could spend part of the wait nearby. Their order was still preserved by the restaurant’s system, and they had to respond when called. During the reported lunch period, the waiting count remained around eight to ten parties. Customers who did not use a smartphone could register at the device outside the shop and continue waiting.
The technology did not abolish the queue; it moved part of the embodied wait into numbers and notifications. Reports also describe older customers approaching apparently empty restaurants only to discover that many parties were already registered. The result is a specifically contemporary Korean restaurant line in which physical arrival, on-site registration, and digitally managed turn-taking coexist.
