How did you do it?

I recently moved and have made friends with a coworker. She has invited my husband and I to have a date night with her and her husband. I am super excited because I've been kind of down and sick of being home. Just got my BFP this week and we are still going to go but I know she wants to get drinks and was talking about the wine cellar at the restaurant. How did you turn down the drinks or get around it? I don't want to share news until my viability scan in 3 weeks because I lost my previous pregnancy by the time I went for a scan.
