'The best heated smoking area in Whetstone...'

This sign made me laugh. So the pub in question, The Griffin, has "the best heated smoking area in Whetstone with a big screen"...



Whetstone isn't exactly the largest area of London - so how many pubs there have a heated smoking area with a big screen? I am guessing just the one. And if there is more than one, what makes the Griffin's HSAWABS the best?

In other words: isn't it enough for the pub to boast that it has a HSAWABS at all? Especially as the Griffin also offers "the biggest beer garden in North London"...
