Yeah I had to ask 3 different people on how to get to it; there's no signage for it.
It's okay... There are some nibbles, and there is beer and wine. I've heard one guy who was frustrated about the lack of whiskey and asked a lounge attendant for it and was brought one. So, I guess if you don't find what you like, you can try asking.
There are no sleep facilities or any other nice stuff; it's mostly a place to chill for a bit. There are showers.
