Do American undergrads drink beer in pubs?

I'm from Florida, for context. I'm sure there's a lot of variation here depending on the place and the year. "Pub" is not really a word in my dialect. I've never been to any place in the US that I would refer to as a pub. I have been to a pub or two in England (which were not what I'd assumed they'd be, since I thought it was just the British English word for "bar"). So for me, right off the bat, this is a really weird sentence (assuming it's indeed meant to be American English). Remember that the drinking age in the US is 21. At my university, there was exactly one establishment that sold alcohol on campus (at the time, things could have changed of course). It was just a casual restaurant that sold alcohol. Among my friends and I, it was a big deal to be able to finally go there and order a drink, after we'd turned 21. They wouldn't have served you a drop without proper ID. (Actually, looking back, I'm not sure you could enter at all if you weren't 21.) Different places can be different obviously, but for that university any of the bars or restaurants near campus were definitely carding (requiring ID to buy alcohol). They aren't dumb, they know there are tons of under-21s around who'd like to get alcohol, and there are stiff fines and loss of liquor licenses (AKA loss of a huge portion of revenue) if they are caught serving those under 21. So, if this is meant to take place on a college campus in the US, it's definitely not in line with my experience. ("Routinely drinking" would much more commonly take place in houses/dorm rooms/apartments/backyards if you weren't 21, and even if you were, a lot of it would still take place there because not all of your friends were 21.)
