Need help ladies

My friend is having her bachelorette party in about a month. I am in charge of finding bars for her to go to in NYC. Here is the issue she wants bars with no cover because we are going to see the Awesome 80's prom and then bar hopping. I know of bars but that have covers. Help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Bars that are fun and no cover. Hope you guys can help me.
