So there were really three narratives going on in this book. Two were highly successful and one I found frustrating, so I'm not sure how to rate this.
The first narrative is the depiction of the author's daily life in Delhi. These were so fascinating and funny. Although the book was written decades ago, it still felt very much like India today. These sections were so entertaining that they pretty much made up for any shortcomings.
The second narrative is a condensed history of Delhi. These were also well-told and entertaining as well as informative.
Where the book suffered for me was in the architectural descriptions. Obviously the author is very into the architecture but I found it very difficult to share his enthusiasm with so few accompanying illustrations. The ones provided were not enough for me to visualize sufficiently was he was so taken by. Therefore, these sections bored me a bit and I had a tendency to want to skim over them to get to the enjoyable parts.
I would definitely recommend this book to anyone wanting to get a general portrait of Delhi
