Well the reason we were going to to the PDF menu was because when they sent changes to the graphic designer they’d do it in InDesign and rather than having to remember to change a website AND a PDFAdobe file we thought we could just upload the PDF. Do you think it would be a better idea to do an export or similar of the menu as a PNG or etc rather than PDF ?
it may be easier to just post a pdf but it most definitely is not the optimal user experience and it does nothing to help your search rankings.
personally when i build a website for a restaurant or bar i prefer a single page site. if the client isn’t cool with that at least try to get as much info on the homepage as possible. especially vital info that people will need to access quickly like phone/contact info to set a reservation, map and address, and business hours.
