For a local service? I don't see why hiding it would be bad per se, yet have it listed on your site.
What I am not a fan of is automated directories that scrape that info i.e. Yelp.

If it is listed on your site, it will get scraped by the lower directories eventually. I could only think of non-perfect citations if a business changes locations. That is a pain as you have to email support on a lot of directories to update your information.I hate Yelp. My friend Chris (crescendo designs) was in that documentary.
Anyway, I guess I heard if you do hide it, you won't have perfect local citations.. because the address is hidden?
