Are you looking specifically for Indian food? Or more broadly, vegetarian food?
Dining hall food is never great in general, but there are definitely schools with much better food than others. Like UMass Amherst and Cornell. Next level down, I’ve heard of UMD, UVA and Duke.
There is a large Indian American population here in NJ and our local schools like Rutgers and NJIT regularly have Indian food on the menu. East coast schools don’t necessarily have worse food than schools in other parts of the country.
I don’t believe you’ll find Indian food on a daily basis in any dining hall. If this is a deal breaker you might want to find a school that does not require you to stay on campus, or has dorms with kitchenettes and cook your own meals.
