Agree, Indian food isn’t as well known in US. It’s more than just Butter Chicken, Naan, and biryani. It’s a whole diverse cuisine. I’ve noticed South Indian restaurants are less common in US compared to North Indian and South Indian food has so much good variety. Dosa, Vada, Idli, Utthapam, Sambal, etc.

I’m Marathi myself and I only know 1-2 Marathi restaurants in my city. It’s hard to find things like Pav Bhaji, Kande Poha, Mugachi Usal, etc. in restaurants. So most of the time we end up cooking at home since we don’t get this food outside.
