A 1957 book gives the location of the Cordial Co., Ltd. as 35, Nathan Road.
I'm not 100% sure it's the right location for the photo (it doesn't seem to match up with this photo), but it's the best guess for now.

Location of this photo
Ok, I think the next photo clears it up. You can just see part of the 'Cordial' name in the top-left of that photo, on the corner of Peking and Nathan Roads.
So this photo is of 35 Nathan Road, but we're looking along Peking Road, not Nathan Road as I first assumed.
