Where to meet Singles in NYC?

I’m looking for some advice for a friend who just moved to Manhattan. He’s a 30-year-old good-looking busy-doctor who’s not into dating apps and prefers meeting women in person. He’s hoping to date and build meaningful connections but wants to approach things in a way that feels natural and respectful.

Are there any good daytime spots, social events, or specific venues you’d recommend where it’s easy to meet single women? He would be open to recommended nightlife options that are more conducive to conversations.

He’s a member at Equinox gyms and wondered if any specific locations or times tend to be more social, or which gyms or classes are even a good place to meet women in Manhattan, etc?

If you have tips about specific cafes, locations, activities, or meetups that attract a single crowd, etc, I’d love to pass them along. Appreciate your input!
