Wander is right on. The only bet would be OCH or QV. If you can move it to a Sunday, you would have much more fun.
I have been in QV at strange times during the day and seen some very pretty girls sitting out by the sidewalk so your luck might vary. LOL!! Last time I was there waiting on my girlfriend getting some stuff from her apartment and having a beer at QV. This was around 3:00pm. In walk two little hotties that I am totally checking out as my girlfried walks around the corner.
Damn women and their timing, I swear they know. Most W.G.'s dont get up real early though so best bet would be late afternoon. The ones I always saw were slightly older Indo women, but still good looking.
Good luck and give us an update.
