“The key to the culinary experience is striking a balance: achieving an end result that is equal parts taste and presentation. In many ways, I consider this process an art. Oftentimes when I plate dishes, I draw inspiration from the aesthetics incorporated in painting.”


As a Corporate Chef of SUSHISAMBA John Um, has mastered the art of sushi, from his precise technique to his aesthetic presentation. Born and raised in South Korea, John developed an affinity for food at a young age, embarking on an international culinary journey that began in his hometown of Seoul.


First influenced by his grandmother’s occupation as a diver, John grew up experiencing seafood in its freshest form, acquiring a taste for aquatic life that would make most youngsters squirm, including sea urchin and abalone. His mother and aunt, respectively, a potter and a painter, fostered his eye for creativity, an aspect of his childhood that has inspired John’s current culinary approach at SUSHISAMBA, manifested in his artful presentations. John views each plate as a canvas, enhancing the experience for guests with conceptually plated ingredients – or as John says “edible art-work” – that highlight the beauty of color and texture characteristic of Japanese cuisine.


Moving to the United States at age sixteen, John ambitiously sought professional experience to broaden his understanding of, and approach to, sushi and Japanese cuisine. In 2000, he became a Sushi Sous Chef at Fuji Japanese Steak and Sushi Housein Tennessee, embracing an opportunity to develop his skill set by learning teppanyaki – an experience that strengthened his ability to simultaneously cook for, and communicate with, guests. Shortly thereafter, John accepted an Executive Sushi Chef and Japanese Kitchen Chef position at Hanabi Japanese Restaurantand Sushi Rosen, high-end establishments, where John oversaw and trained employees in customer relation management and food preparation procedures.


John moved to Nevada in 2009, accepting an opportunity to be an Executive Chef at The Sushi, where he assisted with the direction of the menu, specializing in sushi presentation and Japanese cuisine, while facilitating a seamless relationship between front and back of house operations. Following The Sushi, John became a Sushi Chef at Wazuzuin the esteemed Wynn & Encore hotels, bringing his creativity and knowledge to the kitchen of one of the hotel’s most popular restaurants.


In 2010, John joined the team as Executive Sushi Chef at SUSHISAMBA Las Vegas, an experience that has brought his journey full circle. His adventurous palate, artistic outlook and knowledge of Japanese cuisine shine in his ability to transform ingredients into memorable flavors. Annual trips to Japan and past travels to Brazil and Peru serve as inspiration for John’s ever-growing repertoire and refined technique. Showcasing his culinary creativity and desire for a challenge, John creates an array of original dishes, never repeating an offering. His plates have been lauded as true works of art by such esteemed culinary forces as The Art of Plating and Chef Talks.


In 2013, John was promoted to the role of Regional Corporate Sushi Chef, overseeing operations and menu development at Miami Beach in addition to Las Vegas. He was integral to the opening of the restaurant’s first international location inLondon in the summer of 2012 as well as the opening of Amsterdam in 2017. John’s hard work paid off and in 2018 he was appointed SUSHISAMBA Corporate Chef.

“The detail and perfection behind the simplicity of Japanese and Peruvian cuisines, in combination with delicious Brazilian cuisine, reflects my philosophy that great food is life. This wide culinary playing field and the street art flare thatSUSHISAMBA represents allows me to express my creativity in a playful, inspiring and colourful way.”

An integral part of the SUSHISAMBA London team since its opening in 2012, Andreas has risen from Junior Sous Chef to Regional Executive Chef, leaning on his passion for creative cooking with the freshest ingredients as a guiding force.

Andreas Bollanos was called to a career in culinary at an early age. In 2000 he enrolled in Greece’s highly-respected Le Monde Private Institute of Hotel and Tourism Studies for his culinary degree. Upon completion, he decided to expand his knowledge of pastry with a second degree at Le Monde.

Andreas started his culinary experience as an apprentice in a five star hotel on the island of Rhodes. Shortly after, he moved on to a busy Greek restaurant in Santorini, where he learned the fast-paced nature of large restaurants first-hand, serving 1,000+ guests daily. On his return to Athens, he worked at Aristera Deksia alongside award-winning Chef and owner Chrysanthos Karamolegos. These early days were spent honing his culinary skills in Greek, French, and modern Mediterranean cuisine. Working in Athens, Andreas climbed the ladder from Chef de Partie to Sous Chef in various restaurants including Cibus and Milos.

In 2008 Andreas was introduced to the blend of Japanese and Peruvian culture and cuisine as Senior Chef de Partie of Nobu Matsuhisa Athens. There, he was trained by the Japanese team in traditional techniques, flavours and cooking philosophy, obtaining specialty skills such as tempura and robata.  Alongside master Japanese chefs, Andreas honed his fish-cutting and knife skills, adding the ancient art of making sushi to his growing list of culinary achievements. Having gained proficiency of this impressive suite of Japanese culinary skills, he jumped at the chance for a seasonal transfer to Nobu Matsuhisa Mykonos in 2009, where he continued to work with the Japanese robata grill and practice sushi-making before returning to Nobu Athens.

Back in Mykonos the following year, Andreas joined Belvedere Hotel, a Small Luxury Hotels of the World destination. As Sous Chef in the hotel’s main restaurant, he worked with renowned Australian chef George Calombaris.
