One great gift idea could be a coffee table book about a subject your friend is interested in. For example, if they love architecture, you could consider a book about famous buildings from around the world. Similarly, if they love fashion, consider getting them a book on the evolution of fashion. Another option is to get them a book by their favorite photographer or artist. If your friend tends to enjoy visual stimulation, you can consider getting them a photography book related to a subject they enjoy. No matter what you choose, make sure it has topics or themes they care about, and that the book itself is aesthetically pleasing to the eye.
