We always want something “different” when we eat out. 
I visited India on business quite often. I used to ask my Indian colleagues as well business associates what are their favourite types of food when they bring their families out for dinner, and they’d all say “Chinese”. I was perplexed - why Chinese? I felt Chinese food in India was generally sub-par, whereas their Indian food places were simply amazing, with breathtakingly good cooking.
A couple of them did say, "Why would we want to eat the same (Indian) cooking outside as what we’d have at home. We want something different. " 
In the last decade or so, I noticed Mexican food is now very much favoured, especially by younger Indians when they eat out.
