Simple, i find the local guide program when i was searching for coffee shops about 2 years ago.
I love to drink and taste high quality coffee, and here in Montevideo, specialty coffee shops are a few.
Thanks to this program i was able to find different places, rate them, and show my experiencie with other people.
Every time i want to put better reviews for different places.
For coffee shop owners, this is very helpfull. They can improve their sells and promote their own place for free.
