Can you pay in usd in Dubai mall?

Could you possibly clarify for me, is it feasible to utilize US dollars as a form of payment within the Dubai Mall? I'm interested in understanding the payment options available, specifically whether US currency is accepted as a valid means of transaction. I've heard rumors that Dubai is a highly internationalized city with various payment options, but I'd like to have a more concrete understanding of this matter. Would you kindly elaborate on this, perhaps providing some insight into any potential exchange rate considerations or other relevant details? Thank you for your assistance in clarifying this matter for me.
