Η Google announced today that will add a Q&A function to Google Maps and Google Search for Android device users.
So when you look at a Google Maps page looking for one business the one location, you'll have the option to see questions that others have asked the business, but you'll also be able to ask your own. 
You will then be notified when someone else, or the business owner itself - answers any of your questions.
Questions will be part of the page, so when you locate the page in Google Maps or search on Google Search, you can see useful answers or add equally useful questions.
Business owners will be able to add their answers to inform visitors.
This feature has begun to be released to Android users globally.
