Baron Hau, founding instructor at Gusta Cooking Studio

Founding Instructor

Baron Hau is classically French trained in cuisine and pastry from the renowned Le Cordon Bleu before he paved his path under the guidance of chefs coming from Michelin star restaurants and MOFs.  A pastry lover himself, Baron’s culinary training also empowers him in the realm of gustatory and olfactory explorations beyond ordinary sweetness.

While food is the overarching theme throughout Baron’s career, his gastronomic journey started young.  When he had to live by himself as a teenager, he took the opportunity and exposed himself to new ideas by frequently dining out.  Hunger for knowledge persisted, so travels, experimentations and keen reading fed his curiosity.  In retrospect, the technical acuity and investigative mind were what brought him to his current venture.

Attending trade shows every year to keep global trends abreast, he also strives to bring in the newest concepts, tools, and ingredients to create and let create tasteful results.  He believes that connecting people's love of food will make the world a better place.

Linh Vu is a savoury artist who focuses on the science and flavours of the dishes he curates. Working in the restaurant industry for several years has heightened his expectations for quality and customer service. Starting at the age of 13, Linh developed into a vineyard manager who created and nurtured fields of grapes for winemaking. Although mostly self-taught, Linh has worked alongside several mentors and head chefs that helped to mould his current philosophy of cooking. More recently, Linh was a part of the store opening of Joey Restaurants in Sherway Gardens where he met a team of talented chefs. Linh acted as the saucier by day, and an apprentice by night. Soon after, Linh began his own venture in 2017 called Sumeshi, through Markham’s summer night markets. With a feature in Blog To for Night it Up 2017, Linh was able to share his love for food with others. At Gusta, Linh focuses on a similar concept where eating and enjoying food is an experience in itself. 

Linh can be seen this summer at several night markets like Taste of Asia and Night It Up 2018. He is currently working on producing delicious desserts for Gusta Studios and making home-cooked meals for his loved ones daily.
