How can i write this scene descriptively?

There are 10,000 different ways it could be done. The way you might be inclined to do it could be as different from the way the next author might as goose down pillows are from hunks of basalt rock. You've already set the scene, the only question left for you to answer is how you plan to go about doing it. Expand everything. Put the reader in the pub with the pair of them. What type of place is it? One of those exceedingly dim, astoundingly quiet pubs that smells of deep wood where old men line the bar sipping nips on hard backed barstools? Is it a chic lounge with a ceramic wrap around bar with plush couches lining the walls? Is it one of those pseudo cabaret discotheque type lounges with lots of neon and flecks of glitter laid into the tilework? Why does the second woman engage the first in conversation? What is she doing there in the first place? Is it noon? Eight P.M.? Three o'clock in the morning? What is the woman's purpose in revealing her sexual orientation? It's your story.
