Sure, the US has lots of places with no open container laws. I doubt you are going to go take a taxi outside of the city to drink a couple beers though…

If if were me? I’d give them to a homeless guy, or just leave them in my hotel room. Because yeah, most places either won’t let you bring outside drinks (besides some fancy restaurants where you will need to buy a fancy meal) or will forbid alcohol entirely. Potential to bring them home in a checked bag.
