How can you get Siri to learn Restaurants it doesn't know?

So I keep asking Siri directions to several restaurants in Brooklyn, NY which have been there for years and all it will say is getting directions to the street it's on but not actual restaurant. Now when I go to google maps and hit voice command and ask it finds it perfectly. So I know it's not the way I'm speaking. Oh and all these restaurants are also saves as my favorites in Maps.

So how do I get Siri to recognize or remember them for the next time?
