You are confused Khun fountainhall and your repeated displays of confusion are confusing others.

The name of the Soi is Pratuchai and it is not new. Duangthawee (as BKKguy has noted above) is the name given to the buildings and the paved area between them that line the Soi. Duangthawee Plaza.

Just google the address of Dream Boys or Dicks Cafe and you will find that they are consistently listed as:

38/3-6 Duangthawee Plaza, Soi Pratuchai, Suriwongse Road, Bangrak
and
894/7-8 Duangthawee Plaza, Soi Pratuchai, Suriwongse Road, Bangrak
respectively.

Of course, there are incorrect variations on the www posted by similarly confused individuals.

But now I will add a confusion of my own. Christianpfc will be interested in this: Open up Hornet and zoom into the location of Dream Boys and Dicks and you will see the small street labeled as Soi Decho!

That is not to be confused with Decho Road which runs between Suriwongse and Silom, much further west (west of Pullman G Hotel) of course.....
