It is common knowledge that you have to 21 yrs and over to be served alcoholic beverages in the USA I'm from the UK and have been to the states in 1992 unfortunately my Gf at the time was only 18 yrs and she was asked not to approach the bar ( politely ) but I was allowed as I was 21 yrs ....if the law has changed since then I apologise for being wrong but as far as I'm aware it is still the same .
