I was initially more excited about the ice bar than the museum itself, but the bar was closed for renovation. The museum, however, was excellent!
The exhibits were very informative and interactive with lots of videos about glaciers not just in Argentina but around the world. The staff were also very friendly and helpful. They really made sure that you get to enjoy the complete experience.
One of the staff, knowing I prefer English to Spanish, would inform me when a video was going to start in the English version or would offer to just start the videos in various exhibits in its English versions for me.
I spent more than 2 hours walking around and reading everything.
It was really an enjoyable and educational day at the museum.
