it's pretty much chinese with a little korean. i don't know if japanese guys actually visit. i have visited this spot before. everywhere baits and switches. not every hero wears a cape like OP, running in blind for a 800hr girl.
My comment to the non-Asians who can't get in: you're not missing much. There are a few gems that show up here and there, and more genuinely younger girls (as compared to the "23 year old who is actually 33" that is common in manhattan). But it's 100% fake pics and the price doesn't generally match the typical service.
Props to the few members who review the girls from here and provide the Intel. at lot of members on this site frequent these houses but avoid reviewing to try and keep them UTR (even though they are widely discussed on Chinese message boards and not at all UTR).
