Yes, Super Rich - the one I found is on a side street directly across from the World Trade Center about 2/3 of the way toward Pratunam. (it would have been easier if I had seen the maps in the post below). Two odd things - that they won't take tc and it is the only place I have changed money where I did not get a receipt - just a print out showing the $x exhange rate =# baht.

The sign is orange and strangely they had a slightly different rate (lower by 2 baht/100 usd) posted on the window outside vs going inside (which is air conditioned). Also I was told the rate was 44.10, no matter how much I changed, but when I changed $500 I got 44.12 Good for almost an extra cafe yen(iced coffee)!
