Johnny Walker Blue is good but hardly worth what they ask.
It's typically seen in product placement shots in TV shows about high rollers.
It's a blended Scotch that compares with other $40-$50 Scotches.
They sell it to social climbers for $170.
It's pretty smooth as far as scotch goes, at least in my experience.
But, as said before, it's still an nice gesture to get for someone.
And it's cool to serve if you have it.
Not everyone obsesses over the nuances of everything and some just appreciate things at face value.
