Evos is where old-school fast-food fans go when they're jonesing for a burger and fries. Evos burgers are free of antibiotics and slow roasted in an oven. The shakes avoid the standard fast-food syrups and are made with organic milk and sugar, fresh fruit and juice. Instead of deep frying its fries, it blasts them with hot air in a process it calls air baking. It also uses organic ingredients whenever it can.
