As DGS says try the bars in LKF - Thursday is a good day, as it's Ladies Night
having said that you will need to have some game, and cash ... those girls can be materialistic
If you're visiting, another thing you can try is Craigslist ... there seem to be some girls there looking for no-complications meetings with visitors ... you could try putting an ad. Again, that path needs more game than the walkup / HG option
An alternative would be to visit a couple of walkup girls that take your fancy, then see if she has a "day off" to show you around. If you give BFE you often get GFE in return ... go along in the afternoon lull, take an unexpected snack with you for her, and you'll find the whole thing much more relaxed than at peak times. They get lonely cooped up on their rooms alone.
