In 2009, Hyatt Regency Mexico City decided to refurbish their Teppanyaki Grill restaurant… a masterpiece of their catering pole. The Teppanyaki restaurants belong to the most challenging show cooking projects. It is probably the type of restaurant where the proximity between chefs and guests is the highest one. In fact the guests plates are extremely close from the grill surfaces. This kind of show cooking area points to customer requirements for efficiency and ergonomics in a more undisputable technical environment. The high expectations of Hyatt Regency Mexico City in terms of energy savings combined to the amazing architectural concept of Mister Murai (Hisashi Murai Architect) led to one of Halton’s biggest challenge.
