It's really just one big open room. Food, bar and showering facilities are ok. The lack of availability of computers, business services, and seats are usually my biggest gripes. Fine if you're looking to re-fuel and refresh with a shower but not a great lounge to get an work done in IMHO.
The T2 lounge does have a children's room - like the ones you get in some Admiral's Club lounges - which I suppose is due to the larger number of families flying on JQ? Personally I'd like to see these in other QC lounges.
