I intend to be brand loyal and have a Grey Goose martini (or two).
Ew. It's not a martini if it doesn't have gin.
Worth noting that vodka is, of course, the purest possible expression of branding for the sake of branding- aside from the actually nasty bottom-shelf stuff it is all designed to be exactly the same with no personality or taste whatsoever.
I think I'll have a finger or two of this over ice, maybe with a splash of bitters or Campari if I'm feeling fancy:
Silly name, quality product. Smooth and flavorful, packs a punch, not too expensive.
