I'm stuck in Tokyo until January 13th.  I do not drink, 
and I'm not interested in sex.  I was told I should go to Roppongi, so I 
went there last night, but
 
1. I only saw about 10 Westerners
2. The streets were full of 
prostitutes and scammers trying to get you into
shady nightclubs
3. The 
few Westerners I spoke to said that Roppongi is the wrong place to
meet 
women, especially if I don't drink, and I'm not interested in sex.
Does someone know better places?
