What is Yelp's Secret Sips Society? They describe it as an Easter egg hunt, but there's drinking with friends involved.

Here's how it works;

Download the Yelp App. About 30 minutes before a Secret Sips Society meeting the coordinates to the location will be posted as a tip on the event listing. They suggest you also download  gps-coordinates.org as the location will be posted only as latitude and longitude, no street address, (fun right?)

Once at the location your next move it to find the Yelper who posted the location and tell them the secret catch phrase that will pop up from Checking-In on the event listing.

The first 9 people to do this will have their first drink paid for.
