Us Brits are funny folk.
Last century I sampled many pulls in local brit pubs... while traveling around the country with one of our local reps.
We like our beer warm (well, room temperature or a shade below) and flat,
Not exactly my experience. I saw more room temperature bier consumed in Germany back in 1970... I even kept my flip-top bier bottles stashed along the outside edge of our (army) tent and the September weather kept it pretty drinkable. Curiously the German bars catering to US soldiers chilled the bier and provided the locals with immersion heaters to warm up the bier.
and usually quite dark of colour.
I am a fan of proper stouts and made sport of trying out new black and tan combinations in every new pub we visited. (I also found decent local stouts in Australia).
Even better if it has been hand pumped from a wooden barrel rather than pushed by gas pressurisation out of a metal keg.
As I recall it was "pulled", kind of lifted out with lever-scoop arrangement. The bar maid(?) pulled on the long handle-lever that rotated around a pivot point, raising a portion of fresh bier up that then the spilled out into a glass/mug as it tilted outward.
Some of us do enjoy a lighter and more carbonated style which, in one pub I used to frequent, was affectionately referred to as "Eurofizz".
I am aware of any number of beer variants in the UK, bitter, lager, ale, pilsner (pils may not be brit, pilsner is a German thing). Then there'e session beers that aren't really a different type but lower alcohol version suitable for drinking over extended periods (sessions).
It's probably best that I don't recount the British Ale drinker's opinion of American beers ;-)
I recall the real ale drinkers holding lager "louts" in low regard.
(really, I jest - your cutting edge micro-brews lead the world and, in places where it gets considerably hotter than here, there is a lot to be said for a colder and lighter concoction)
Since I brew my own, I find most other beers inferior (because they are). My primary criticism of US microbrews are that they are generally over-hopped to impress inexperienced beer drinkers. Some don't suck like the mass market piss-water.

PS: The old joke about Brits drinking warm beer was because their refrigerators were designed by the same engineers who designed Lucas electrical systems used in the Brit sports cars. :-(
