My humble advice is stay away. Big surprise, eh?
I had a chance to go to a Christmas dinner and I declined because it was in a bar, even though I know the people there would not have cared if I didn't drink. You'll know when you're strong enough.
Find a sober friend and/or family and just hang out, play games, whatever. It's just another night. It's just another night. It's just another night...
You can do this.
Take care of yourself.
