Well I guess I will help out here.
I have used 10,000 Yen Roppongi quite a few time with good results, but i will say I have never paid 10,000 yen. They do seem to charge foreigners addintional 2000 Yen above whats posted on the web site. The Operater does speak enough english to get your details room number, location and course, but I wouldn't want to try to carry on a coversation with him. With that said my Japanese is not that bad so commication has never been a problem.
The girls generally range between 5-7 with an occasional 8-9. I can tell that they will try to send a girl that can say at least "Hello" english but most of time they do not speak english at all. Reguardless of the course the girls seem to follow the standard rules shower, kissing, body licking, and a BBBJ. Some do FS some do not, it seems it's more up to the girl and falls under YMMV, I have never asked a girl for FS either. I have only had one bad experience with them and again that falls under YMMV.
