Congrats on your pregnancy!

What we did:
I ask DH in a restaurant if he wants to share a bottle of wine (group meal). He says no, he's driving, we'll stick to fruit juice.
I drove a lot more!
"My GP gave me some tablets and said to avoid alcohol." - the tablets were folic acid.
Nurse those drinks!
Drink unfermented grape juice in a wine glass.

Foods I am picky about anyway, but don't make a show of avoiding food, just pick something preg-friendly instead.
