Jason Inniss was born in Barbados into a family-owned bar and restaurant. He was raised in the industry until he left the Caribbean to continue his education in Canada. Jason attended St. Andrew's College in Aurora to finish high school before moving to Sackville, New Brunswick to attend Mount Allison University. After receiving his Bachelor of Arts in history Jason moved to British Columbia to pursue his passion for cooking. Here he took a job on a private yacht as the chef and traveled extensively up and down the west coast of North America for a year. Jason discovered many cooking techniques and styles while on the yacht.

After this he enrolled in the Dubrulle Academy of French Culinary Arts in Brirtish Columbia where he earned his chef degree, with honors. While at Dubrulle Jason also worked at Cioppino's Mediterranean Grill under Chef Pino Posteraro and quickly moved his way up through the kitchen brigade. Cioppino's was voted the number three restaurant in Vancouver by Vancouver Life Magazine that year.

Jason left BC and moved to Toronto where he was quickly employed by Marc Thuet at Centro Grill and Wine Bar. Working at Centro taught Jason the speed and precision necessary to cater to upwards of 300 people a night. Jason left Centro when Marc Thuet approached him to help manage his new venture, the kitchen at The Fifth. It was also at Centro that Jason met his future business partner and best friend Bertrand Alepee.

Jason worked at The Fifth with Marc Thuet and Jean-Pierre Challet as the sous-chef. Here he was given his opportunity to shine, as he was responsible for food cost, labor cost, inventory controls, ordering food, planning menus and events, as well as hiring and training staff. In the three years Jason was employed at The Fifth, it received honors for Best Restaurant, Second Best Restaurant, and Best French Restaurant consecutively. At The Fifth Jason also worked with ten guest chefs from around the world. After three years at The Fifth Jason decided to pursue a dream of traveling to one of the birthplaces of modern gastronomy; France. This dream would not come to fruition yet, however, because on a quiet street called Tecumseth in downtown Toronto, another dream was stirring.

On June 20 2005, Jason and Bertrand opened Amuse-Bouche Restaurant, at 96 Tecumseth St.
