Gusto 501 is the latest restaurant by acclaimed restaurateur Janet Zuccarini located in downtown Toronto. It is the towering new space with an all-glass facade that creates the illusion of floating levels, thanks to panoramah! ah!60 three-panel guillotine system. The street-facing glass façade opens using a counterbalance system to raise and lower three six-meter-wide glass panes weighing a ton each. It is one of the largest operable glazed walls of its kind in the world.⠀
