I travel to Delhi on official tours by flights only. So I have traveled in this train only once, and it was in 1AC, along with my family. It was a great experience, as if it was a tour package by itself. There are two pantry cars, and one of them caters only to 1AC. Freshly made hot home-like food, combined with courteous staff, is something that I cannot forget. Toilet and bathroom (yes, I took bath) were clean enough to give me a feel as if I was at my home. Overall, a great experience, and given an opportunity, I shall travel again.
