[5] Mandarin Oriental, Las Vegas was designed by Kohn Pedersen Fox,[6][7] with hotel interiors by Adam Tihany.

[14] The hotel offered a focus on personalized customer service, and it aimed to attract a high-end clientele.

[10] Mandarin Oriental opened amid the Great Recession, and saw a disappointing financial performance during its first year, prompting increased marketing and promotions.

[4] It contains 389 hotel rooms and suites, and 225 condominiums,[24] as well as a two-floor spa, 12,000 sq ft (1,100 m2) of meeting space, and a pool.

Rooms included a touch-screen device capable of ordering food service and controlling features such as lighting.

[26] Mandarin Oriental opened along with Twist, a 74-seat French restaurant by chef Pierre Gagnaire, marking his U.S. debut.

[27][28][29] Other food and beverage amenities included a sushi and noodle bar, a high tea lounge, and a pastry shop.

[28] In 2017, the Sky Lobby introduced a humanoid robot assistant named Pepper to greet guests and provide information.

[30] In 2023, the lobby was moved to the ground level as part of renovation work, while the Peacock Alley tea lounge will take the vacated space on the 23rd floor.
