"Bar" is certainly the catch-all term in the U.S., but "pub" is also very widely understood to refer to a specific type of bar, especially (but not limited to) bars deliberately styled as Irish or British pubs.
Come to Virginia, where it's outright illegal for any establishment serving alcohol to not also serve food (and not only must food be served, it must account for at least 45% of revenue).
Do they make you order food with every round of drinks? I remember hearing about places like that from my dad, and it seems it would have worked better in the era of cheap drinks/low built-in alcohol taxes.
I went to college in a county that only allowed alcohol sales with food for clubs (think: country clubs). So, of course, the restaurant that I worked for created its own club. You simply filled out your name (and maybe phone number, I don't remember) on a piece of paper when you ordered your drink.
