The US has a wild variety of drink laws that vary by state.
Many states have government run stores, some states allow beer and wine at grocery stores, but liquor must be sold in a separate store. Some states have laws that ban sales after 8pm, some 2am.
Utah is the worst because they limit the alcohol percentage in beer (Mormons don't drink and pushed for these laws) so the companies have to make special shittier Utah beers.
In some states you're not allowed to see the drink being made (maybe also Utah - can't remember) so they make it out of sight and bring it out.
Some counties are dry and you have to drive to the one over (usually lots of stores at the county line). I think some southern states have drive through liquor stores.
One reason I was happy to move to California is the lack of these 'blue laws' [0]. California may have a lot of signs warning you that everything causes cancer (and make it really hard to order a new shower head), but their alcohol laws are pretty permissive.
I don't know if there are any states that don't have open container laws - which is too bad, drinking PIMs in the park in the UK was great fun, and beers outside talking to people is a nice part of the London pub culture that would go well in American cities.
