The sample for this study was the Warung Tegal managers in the Administrative City of South Jakarta. The results of the study showed that the fish at Warung Tegal is usually sourced from the nearest market, but the menu does not take into account the requests of the consumers and is never marketed through digital marketing due to the lack of knowledge in this field. The manager of Warung Tegal also stated that the restaurant's income has been reduced as a result of the Covid-19 policies.
