There should be no issues using points at Restaurants, you just have to make sure you indicate that you are using points before they give you the bill.
There are ofcourse blackout dates like Christmas Day and this can depend on location so best is to call/email the restaurant/hotel in advance and check if your points can be used on the day itself.

(I could, if necessary, use a voucher, but I’d like the flexibility of using the instant award.)
