I would go for the 01. Approach.
But i always try to have a c0cky humorous approach instead of the boring interview cold approach.
I never show too much interest in the beginning from my words but from my actions such as strong eye contact for example.
Showing too much intention from the get-go usually leads to a woman playing games unless she is a healthy one which is rare to find nowadays.
Also being direct is not that is bad, is that is too much investment from you side and you show all your cards from the beginning to a woman that may or may not be f3ucking around with another 5 dudes. You probably will not care, i get it. But it should be equal-to-equal you show your intentions by cold approaching her this is more than enough of showing an initial level of your interest towards her.
Keep it funny, light, actions speak louder than words in terms of body language and eye contact, grab the phone number and move on.
