Well I guess they are for a 50ml shot, but it's still very expensive and like you say the bottle prices are just a joke. There's a whisk(e)y bar across the road from where I work and it's about 1/2 of the price per shot.
Don't forget they'll add 12.5 % to your bill. According to one customer review, this is not optional, insofar as you'll actually have to kick up a fuss and refuse to pay (or else stand up whilst drinking !!).
Rock Hill Farms £350 a bottle
It's £40 from twe.
