ARIA is spread out over two levels of the China World Hotel. Larger-than-life murals of Renaissance-style artworks line the entry-way into the comfortably appointed seating areas, bar counter, and wine bar area, as well as provide dramatic covering for the walls of the Dining Rooms. The unpretentious ambiance of ARIA is reflected in the attire of the service staff and their unobtrusive style, focusing attention on the guest who, whether casually or formally dressed is made to feel equally at ease. Bathed in a healthy dose of natural light from the sky lights and picture windows by day, the lower level has a seating capacity of 100, with a bar counter that caters to the elbow-bender crowd while cozy seating arrangements allow for more comfort and privacy. Nestled on the other side of the room is a wine bar. Soothing jazz add to the cozy and cosmopolitan ambiance of the room.

Walking up the impressive spiral staircase to the upper level and to the main dining area with two private rooms , one is greeted by a virtual show-time of chefs in action as they prepare delectable dishes for and interact with guests.

ARIA Bar & Grill, named after the operatic aria, epitomizes entertainment in every respect: in the enjoyment of good cuisine prepared with fresh ingredients, fine wines, live musical entertainment, and generally a place to see and be seen. It's a place where dining, wining, and having a memorable time comes at a reasonable price.

Known for its fusion-style cuisine composed of the best of the West with Eastern influences, there is a set menu for lunch in the Dining Room and a bar lunch. Dinner is served a la carte.
