I definitely see a difference in drinking culture. In the UK, it was SOP for me to hear people of all ages talk about going out to the pub and potentially getting very stupidly drunk. And there was no embarrassment about it.
In the US, by the time you hit your late 20s or so, people may still drink, but it's less likely to happen at a bar. It's more likely to be a BBQ or tailgate or some other gathering at a home. So I agree with June Cleaver above, but IME, the food list is followed by making sure someone is bringing the beer or wine.
I found, in England (and I lived in many places throughout England), that drinking and drinking a lot was much more acceptable across the board. I find in the US that people drink less in general or at least don't let you know about it.
For example, I knew a couple in England who rountinely drank a bottle of wine between them every night with dinner. Actually, I knew many couples like this. But in the US, even those whom I know to be real wine connoisseurs don't drink that much. They typically save it for the weekend or limit themselves to one glass.
I'm not going to weigh in on what is better lifestyle choice. There's loads of people out there who say that Americans drink just as much, they just hide it or are prudes about it. And there are loads of people who say the UK is in serious trouble with it's drinking culture.
I don't miss the messy town centres of England on the weekends. At least here in the US (or in Baltimore) it's confined to specific areas and there are plenty of other parts of the city to go to that won't be overrun with vomit and pee.
Just my personal experience.
