What call to action belongs in the bio?

The bio carries one ask: book a table on WhatsApp or on the channel the floor actually watches, with the neighbourhood and the hours a reply comes. A bio full of links to the site, the blog and three menus gives nobody a choice they can make. Confirm the link opens the right chat and that someone has it in their pocket during the shift. The button says book and lands on a site that will not load on a phone, or on a form the floor never reads. The bio rewritten with the neighbourhood, one ask and the hours a reply comes, tested from a phone that is not the venue's.
