Does TikTok work for a restaurant whose guests are local?

Yes, when the people who already fill the room also watch short video and the cut shows the dish, the neighbourhood and how to get there. It does not help if the content is made for strangers in another city and nobody in the venue would recognise the door. Ask on the floor for a week whether anyone saw the venue in a short video, and film only if that answer shows up. The account opens, a dance is chased and the comments ask for the address of a place that is not this one. If it is used, it is four cuts a month shot in the venue, with location and booking, and it pauses if in a month the floor saw not one table come from there.
