If dining in, are guests required to produce a copy of their vaccination card?

If sitting indoors, yes, but 90% of our seats are outside (under clear tents and heaters), where a vaccine card is not necessary.

Yes it's required.

Yes. But not for outdoor. However, if you are here for the Sunday brunch, I think they should check for the vaccination card because you have to get the food from an indoor room

Only if dinning indoors, but not for outdoor/patio seating
