You ride the elevator to the sixth floor of ICONSIAM, and Great Harbour International Buffet opens into a grand dining hall with space for more than 400 guests, a waterfall wall reception feature and partial views across the Chao Phraya River. The restaurant formerly traded under the name CP-Hilai Harbour, and its origins trace to Taiwan, with the current incarnation on Charoen Nakhon Road inside one of Bangkok's landmark riverside malls.
