Is the ITC 1:1 buffet offer available on add-on cards as well, or only on the primary card?
From the official HDFC website (source
here), one can traverse to the T&C page.
And as per Serial No 14 of the T&C of the offer (source
here), "Offer applicable only if primary cardholder is one of guest who will dine at restaurant."
So, it means that the offer is applicable only if the primary card holder is also present for the buffet.
Hope this helps.
