Best bars in NYC to find a third? MF4F

I M29 have been casually hooking up with this girl F24 for just under two years and are looking for a third for a threesome.

Wondering best spots to find one? Would like in person as opposed to virtual because would like to see the vibe / cleanliness of the person.

If you have any spots for normal-ish people, please let me know. Also apologies if this is not the write forum for this type of q
