I have to say I am not a regular user of T2, but on one of my in frequent visits I noted shortly after opening that it was rather uninspired and indeed seemed to be short of places to sit and indeed toilet facilities from the queues outside. Externally it looks like a municipal bus station and is not much different from Liverpool in that regard.
The last time I went through talking to a sales person on a perfume concession she said the place was already falling to pieces with failing Air Conditioning / Lifts / Lighting etc. etc. I have not been back through there since July.
Cheers
