First of all, restaurants are not interested in anybody’s health. They are simply liability averse.
Second — I think it’s OK to feed booze into pregnant women. Short of regular alcoholic binges, there is nothing harmful about a pregnant woman having an evening cocktail or a glass of wine with dinner. I really have no patience with the nannying and shame-mongering of prohibitionists.
And before anyone objects that no doctor will name a guaranteed safe level of alcohol consumption for pregnant women, consider that no doctor will name a guaranteed safe level of anything.
Safe level of alcohol? That’s easy.
None.
