Not sure what you mean by no cafes like Poland.
Well, you'd have to ask my friend :)
A café in Poland is called "kawiarnia" and it's not the same as pub or restaurant or sweet-shop (or how you call it in English)... You can usually drink coffee there, tea, wine and eat some cakes, ice-cream.
Here's the place where we were with my friends and where my friend from London told us that there are no cafés in London (it used be our favourite, we were going there as students, it's very small but it was very popular, packed with young people):
It's called "Wesoła kawka" ("Merry Little Coffee"). "Kawka" in Polish means coffee, but it's also a name of a dark bird (Western Jackdaw):
But it's also a surname of a writer Franz Kafka and the toilet at that café was painted all in red with quotes from Kafka written all over the walls in golden paint, with some drawings and with funny and witty texts and other word puns connected with word "coffee" in Polish, written also by the clients :))) Probably my favourite toilet xD
Another typical little café in my city where students come:
More old fashioned ones:
Do you mean a couple of people buy a coffee and then spend the next couple of hours chatting and staring at an empty cup? There are thousands of cafes in the UK but people generally just go to have something to eat and leave shortly after. Of course people do meet there also for a coffee and move on without spending hours there.
Interesting, that's what she partly said, that there are places like Starbucks where you wait for your coffee in a line or sth, you get it in a plastic cup and you go out. She said that people in London are often in a hurry and there's no such thing like sitting and talking for hours in a café. People sit in pubs, I think she said :)
Of course something could change, it was quite some time ago when she told us about it.
That's what café is all about:
As the name suggests, coffeehouses focus on providing coffee and tea as well as light snacks.
From a cultural standpoint, coffeehouses largely serve as centers of social interaction: the coffeehouse provides social members with a place to congregate, talk, write, read, entertain one another, or pass the time, whether individually or in small groups of two or three people.
Most pubs will sell you a coffee nowadays and you can hang around for hours, without the fear of being thrown out for not buying anything else:)
We could hang around for hours in cafés and we've never been thrown out :)
