It is quite nice. Located on the left immediately after security, it has seating for around 80 which would seem to be more than enough most of the time. It's decorated in a similar style to the new TG lounges in Suvarnabhumi, and has the usual domestic selection of snacks and soft drinks. There is also a very expensive looking massage chair, which appears to have about 200 different functions. Unfortunately I didn't give it a go, as I didn't have time to read the huge instruction manual hanging from it's side!
