I try to tie an advertisement to highlight a specific story, so if any of those places (with the exception of the Daily Planet) are a center of focus in a story... let me know, otherwise, I feel they're already covered in canon.
I was thinking the inn (or is a B&B) where Lois and Clark stay in "High Tide" might also be a good example. Or a specific restaurant they might eat at (such as Morgana's Cafe Americana) works. If there was a fic set specifically in the Metro Club or the Magic Club, then I might highlight the new aspect shown in the story. Or if there was a specific new industry in the Luthor family (like his L.L. Clothing line for Men, I highlighted last year from "Green-Eyed Monster").
