Tetsu was a modern Japanese restaurant conceived by Michelin-starred chef Masa Takayama, Tetsu served a Robatayaki-based menu with an emphasis upon grilled fare. The first location opened in the Aria Resort & Casino on the Las Vegas Strip in 2012, replacing Chef Takayama's Shaboo, which had occupied the space since 2009. In November 2017 a second branch opened in the Tribeca neighborhood of New York City. The New York location featured a casual ground-floor space for a la carte dining, and a separate cellar space named Basement which served fixed-price omakase meals.
