I know that the drinking age is 21 in every state, but I have heard that you can drink liquor at restaurants under 21 if your spouse or parents are with you in some states. Is that legal in Texas? Every so often I have a glass of wine with my parents at home. They don't usually drink wine when we go to a restaurant, but could I get wine if they were there and said it was ok?I don't think your right. On Yahoo answers someone asked if a minor can drink wine at a restaurant if their parents are with them in Texas. The people that answered the question that a minor can drink wine at a restaurant as long as their parents or spouse are with them. I'm not sure which is correct. I think you are just giving your opinion on what is right. If that is true, post the law that says a minor can't drink wine at a restaurant if they are with their parents so that I can read it. Thank you, John Curtis Rentz. I thought that you could drink wine at a restaurant with your parents or spouse as long as they are there with you.
