Some states do not allow those under the legal drinking age to be present in liquor stores or in bars (usually, the difference between a bar and a restaurant is that food is served only in the latter). Contrary to popular belief, only a few states prohibit minors and young adults from consuming alcohol in private settings. The National Institute on Alcohol Abuse and Alcoholism maintains a database that details state-level regulations on consumption and sale age limits.
