My mum was actually told by her dr to drink a stout a week with me to keep iron and vit b levels up! I also had a night on the tequila spammers before I found out i was pregnant, but when I found out I was worried sick about if it'd effected her or not.

I know others that have been told to have a glass of wine (after 1st tri) to relax as stress was more likely to hurt bub than a little bit of alcohol was. Personally I didn't drink any tho until after she was due, and even then I only had 1 midstrength beer.
