It's generally true that Indian lounges have better and more food variety than most International lounges. Where most lounges outside India especially Europe excel is in liquor with almost all lounges having decent free liquor.
Also crowding is a major issue in Indian lounges, esp Del & Bom
Occassionally, I have seen crowding in lounges globally but not as bad or consistent as India, most likely the reasons are most Indian airports have very few lounges and almost complete lack of Airline lounges. All of this made worse by reasonably easy lounge access.
