If you are looking for a magazine subscription that is somewhat unusual, you could try Art Culinaire. They are actually hard cover books with no advertising rather than your typical recipe magazine, so rather hard-core, but someone who is really interested in food might enjoy them. They have recipes, lots of nice photos, and chef profiles. I'd say it is geared toward professionals, sort of the American version of the fabulous Thuries Gastronomie magazine (which I would recommend if she reads French).
And a freebie: she should check out my friend Shola's blog, not recently updated,, but filled with inspiring photos and loads of interesting ideas: http://www.studiokitchen.com/studio-kitchen (I am pretty sure it was he who gifted me my first issue of ArtCulinaire.)
