The Dux de Lux originally called Llanmaes, was a popular beer garden and restaurant in Christchurch, New Zealand, that is part of the Arts Centre. The building, initially a private home, became the home of the student union of the University of Canterbury at this central city site before the tertiary institution moved to the suburb of Ilam. It is listed as a Category II heritage building (register number 4907) by Heritage New Zealand. The building was closed following the February 2011 Christchurch earthquake, with the restaurant and bar moving to various suburban premises.
