Hmm, how to explain this? There is a nice Thai place nearby…
The Hyatt is next door to the World Trade Building. Walk out the front door and across the street. Go through the park opposite the Hyatt, and cross Renai Road. Walk past the bandshell (you are now opposite City Hall) and cross a small street - SongKao Rd. You will then be facing an apartment block. Just walk around to the back and there is a pretty good Thai restaurant there.
