Colours By The Bay introduces a novel concept in dining experience. It brings together different restaurants under one roof to offer diners a choice of specialised cuisines ranging from Chinese to Korean, Thai, and Italian. It also includes Singapore's hottest nightclub, DXO Club.

The restaurants making up Colours By The Bay are established names with a strong following. They are ThaiExpress, Jang Shou Korean Charcoal BBQ, Urban East Bistro & Restaurant, Al Dente, and 2 Hot Halal Cafe. Each restaurant occupies about 2,000 sq ft of space. Al Dente is spread over two floors, as is The DXO Club which is the largest at 12,000 sq ft. Together they take up over 26,000 sq ft at Esplanade - Theatres On The Bay, including a 4,000 sq ft out-door area.

Each of the outlets is differentiated by Colours and design rather than separated by walls. A common design theme runs through each of the restaurants to tie them all back to Colours By The Bay. The place has a vibrant, trendy and hip feel. The relaxed ambience provides the perfect place for patrons to have fun and enjoy themselves. The interior is designed by well-known design consultant David Broadley Associates. Colours By The Bay can also cater for official functions and celebrations such as corporate launches, annual company dinners, weddings and birthdays.

The name Colours By The Bay reflects its relation to Esplanade. It also alludes to the different cultures and races that have given rise to the different varieties of cuisines around the world. The logo has different colours to represent the restaurants making up Colours By The Bay. The waves in the logo signify the water in the bay while the different colours also bear semblance to an artist's palette.
