Motown II is THE place to pick up freelance girls in Roppongi. It is dead early in the week, but from Weds onwards it gets very busy, and Friday nights are often so crowded that its hard to walk the length of the bar. Not sure why this has become the premier place for this kind of action, must be some kind of management policy encouraging it. All sorts of girls, from Japanese girls looking to get laid (free, ugly) to foreign amateurs and pros. The later you go there, the more the choice, as the girls come out of hostess bars after the trains stop, and call at Motown to score for the night. There are a lot of regulars and depending on the night, many "drifters" from all over the world.
Yes, there are a lot of ladyboys there. There has always been a scene of Pilippina trans-sexuals at Motown. Most are pre-op, most are spectacularly built, and if you like that sort of thing (I do) its a great place to go. If you are anti (and I'm not interested in your comments about my own preferences, thanks) then please be careful, there are a couple of post-op "girls" who are absolutely convincing and rather less than scrupulous about full disclosure...
911 - I try here when Motown is busy, and its pretty hit and miss. I've had some great experiences, picking up young and nubile girls, friendly, happy to come back to my hotel and spend the night (after trains have stopped) for JPY20,000. On the other hand I've been skillfully worked for drinks all night and then the girl disappears while I'm in the toilet... you wouldn't have thought it worth all the work on her behalf for a few drinks! Much more a freelance / amateur place, with lots of non-P4P girls mixed in with the pros. Fun if you have lots of time, like to flirt / work a bit for your conquests, and you can come away with freebie winners occasionally - but if you are after walk-in walk-out Motown II is a better bet.
Other bars - Wall Street II is an empty shadow of the original WS Bar. The Irish bar across the road can occasionally be fun, and is a good place to play pool (reserve a room for JPY2,000/hr) and scope out the talent. There are lots of other bars, but none that I've reliably enjoyed, let alone scored in.
If anyone else has any recommendations, please add them to this thread. Cheers
