Hello,
Yes, there is only 2 gogo bars, there are in Soi green Mango
http://gogo-samui.com
Soi Green mango has a U shape, and the one i have been was at the right entrance of the Soi.
But like u can see they have a commun website, so i guess its maybe the same owner.
Like usual, its not in a gogo than u going to find the most beautiful girls of the island, but its there than u will find the most crazy one (in a good way).
to find FL, u can read info on this website :
