As they were not very busy today, I was afforded a tour of their executive lounge on the ninth (top) floor.
It looked quite pleasant.
Pullman Tokyo Tamachi Executive Lounge
Unfortunately, that's pretty much the whole place. I think maybe 20-25 people can sit in there. From what I was told, there are about 40 rooms that come with lounge access, and of course all Platinums get access as well. So if this hotel should ever become popular, I can imagine this place becoming
really crowded at times.
Here is the view below. Great for train enthusiasts!

From the other side of the building, you can currently see the Rainbow Bridge, but that view will eventually go away when the additional office tower starts getting built next year.
