    When we walked into the cafe, we were greeted by a waitress who smiled, held out a menu, and pointed to a table. It's only when we asked for a table for six that we realized something was a bit different. The waitress glanced at our group and held up six fingers. That's because all the staff are deaf.

Last month, the Huffington Post visited Smiles Cafe in Granada. The business only employs people who are deaf, from the waiters to the cooks. “My goal is for this cafe to be a mirror for other businesses to lose their fear of hiring people with disabilities," the founder Antonio Bunuel, who is from Spain, told HufPost. “It's also for the people who work here to lose their own fear of getting into the work force," he added, “So they can fly.”

In the city, about 1 person in 15 has a disability. But around 99 percent of people with a disability are unemployed. While the law requires companies to employ two people with disabilities for every 50 employees, many businesses don't. “Smiles Cafe was born out of a provocation. 99 percent of people with disabilities here are jobless. That was wrong!" Bunuel said. “So I decided to open a cafe where all of the employees were deaf to show that it works.

At the cafe, customers order by pointing to items on the menu, which have special symbols to indicate substitutions. For instance, if you're ordering fruit parfait, and you don't want yogurt on it, you just point to the illustration (图示) of the parfait, and then to the image of yogurt with a big red “X" over it. To help customers communicate with staff and learn while they eat, the walls are covered with letters? words and phrases, from “Thank you" to “Welcome" with illustrations that show the corresponding translation. The cafe, now five years old, is a project of the non-profit Centro Social Tio Antonio. “We've opened a small window," the founder said, “If it serves to create awareness, then that's a start.
