I feel like most of the advice in here about night game, assumes the girl is on her own, how do you handle big groups?

99% of the time I see a cute girl in a bar or club, she is with the group of 4 or more friends in a circle dancing or talking in very loud envrioment, I feel like I can’t open her.

When I go dancing salsa and stuff it’s different because a lot of girls are on smaller groups or break off from the group at any time. But that doesn’t happen with normal clubbing/party scene How do you handle that?
