Influencers, youtube videos, articles, google maps review may deliver information about pick-up places. The internet relies on visual things. So, they may show you beautiful women in a nightclub but it does not mean you will find these women if you would visit this place.
Don’t forget that lounge bars and nightclubs are commercial places. The owners of these establishments are very pleased to know that you are convinced you will meet a woman in their premises.
For your information, In Latvia and Canada, I saw that nightclub and bar owners hired fake regular female customers to encourage men to spend their money.
Don’t focus on the night establishments. I know it seems obvious for a tourist to visit a music festival, a nightclub or a bar to meet women. I have never met the best women in one of these places. I have met the best women in semi private places like: hostels, hotel club, fitness clubs, salsa club, Equestrian center. In my experience, women can be hardly met in public places. They don’t need to socialize. People (both men and women) naturally approach these women.
So, you must think out of the box.
