DR Singdaw, I love the Metropolitan Room.
I understand what you mean about it getting very crowded there, though.
If it's a sold out crowd, the room can be quite packed, and you can really feel like a sardine.
But there are some tables that are better than others, if that really concerns you.
As Fred said, the tables on the upper level are less packed, although you then have a side view of the stage. There are also booths line the back wall that are more centered in front of the stage and provide a great view - but comfort depends on how many people are sharing the booth. Three people is ideal, and very comfortable.
It's really a beautiful room, and a lovely place to see cabaret. The staff is also very friendly and accomodating, and they work very hard at being as non-disruptive as possible to the performer and audience when they are serving drinks.
