A quick search tells 5 guys burger prices are about same in US dollar vs UK pound ..e.g $9 here 9 GBP there. So yes, high price, but if anyone last few years still thinks that fast food is cheap and kind of daily thing is a victim of marketing myth.

It doesn't help that how its sneakily promoted by TV shows where beat cops, blue collar workers eating burgers and shake all the time where IT engineer like me would balk at such high prices
