Studio Tour


Baron Hau, founding instructor at Gusta Cooking Studio

Founding Instructor

Baron Hau completed his classic French culinary and pastry training and obtained Le Grand Diplôme from the world renowned Le Cordon Bleu. He trained under chefs who came from Michelin star restaurants and pastry chefs of high calibre, including Chef Christian Faure, who have attained the highest MOF honour in France. A pastry lover himself, Baron’s training in cuisine also empowers him in the realm of gustatory and olfactory explorations beyond ordinary sweetness.

Baron’s gastronomic journey started young. When he was still a teenager, he was left to live by himself, which gave him the opportunity to manage his own food early on. He gained a discerning taste from frequently dining out, and learned the diverse culture of foods from travelling and keen reading. Combining classic training and knowledge in modernist gastronomy, he is now able to create desserts and dishes of innovative flavours that tastes extraordinary.

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.
