What gift to ask from boyfriend?

He got a promotion and wants to buy me a gift which is so sweet but nothing comes to my mind. I don't need anything. I told him maybe we can go out and have a romantic dinner date but he says that is not a gift. He said he wants me to say something because he is not good at buying gifts and doesn't want to mess it up. What can I suggest him to buy?
