How is this getting hits without keywords?

I've gotten into the habit of searching on Google maps when I need a specific item or service. For example, if I search for "fancy feast" meaning the cat food, I get Petco and PetSmart but also a handful of restaurants that I'm sure use those words in menus. But I just searched something very specific "microdermabrasion" and it hit on the services page of a place that does not do that. I searched the page and the source code for the word and don't see it. How does that work?
