Sirocco is the world's largest all open-air restaurant and "Sky Bar", located on the 64th floor of the State Tower in Bangkok, Thailand, which is the second tallest building in Thailand. The 150-capacity restaurant opened its doors in the winter of 2003. Its main feature is a spectacular 270° panorama of the Chao Phraya river and Bangkok city. Sirocco was designed by global architectural and interior design firm, dwp | Design Worldwide Partnership with the design team led by Executive Director, Scott Whittaker.
