I used the new lounge at King's Cross today with the 50 point online redemption.
There is no reception desk as such, you simply enter and the assistant may come and ask for your ticket at some stage. I noticed also that the toilets were separate from the lounge.
The complementaries were all as expected: tea/coffee, orange juice, apple juice, 330ml cans of Coca Cola and Diet Coke, bottles of still and sparkling water, two types of biscuit, expensive-looking ready salted crisps, a selection of fruit and a copy of The Independent. Toilets were very clean and had a hand soap with separate moisturiser.
The assistant was restocking the fridges when I arrived and the lounge looked fairly busy (someone at every table). As usual, I appeared to be the only one eating any fruit!
I didn't take any photos as it seemed rude whilst there were people relaxing.
I was impressed. Wouldn't pay a fiver, but I'd definitely spend another 50 reward points on this.
