I was there last week and if you could pay in cash, take your full vaccination card or certificate anyway, because in all restaurants they ask for it just like in museums.
It can be done in cash and you need the vaccination card and identification with a photo, you can take it in a digital photo on your mobile.
If they ask for it
If you can pay in cash, and if they ask for it.
If you can pay in cash and if they ask for a vaccination card.
