If you happen to be in a city, then one of the best places to find women walking around is in the malls. These days almost all medium to big cities have malls that are active from early morning to late night.
There are pubs, clubs, coffee places and so on frequented by women who may be single or come there in groups. How to approach them for dating? That is something you have to decide as an individual.
As per the many surveys of singles, especially in the USA, most of the flirting never moves towards relationship due to the initial hesitation. Parks, gyms, yoga classes, book reading clubs and such situations attract beautiful women as well.
