This month, Chilis announced it was purchasing 45,000 Ziosk tablets to distribute across more than 800 restaurants nationwide, the largest tablet network of its kind so far. By this fall, guests at nearly every Chilis in the country can place orders, play games and pay their checks from our tabletop tablets, the Ziosk CEO said in a statement. Smaller networks are already in place at Applebees and Pizzeria Uno, suggesting an industry-wide trend. So why are restaurants opting for Ziosk and its competitors over commercial tablets?
