Yes, it's worth the hunt. The pizza is great!
We tried the sausage and pepper slices. The hallway (covered in old album covers) was a nice diversion too. David Bowie's "Ashes to Ashes" was playing as we entered the hallway and we couldn't resist singing along!
Three clues:
1. It's in the Cosmopolitan.
2. It's unadvertised anywhere.
3. Third floor.
That's all I'm saying.
Enjoy the hunt and enjoy the pizza!
I also noticed some classic arcade games. Anyone remember Galaga?
