Sazanka which used to be in Washington Square near Bourbon Street Bar etc, has moved.   The address is now 160/4-6 Thonglor Soi 6 (soi Sukhumvit 55).   I don't know where that is in relation to the BTS Sky Train which is what I'd normally gauge it with.   Anyone with more more accurate details please share them.   Looking at Google Earth it looks as if it could be a long distance from the Sky Train.
