Agreed. You should always check and with all things there is no guarantee but when Jain style is requested, Indian restaurants generally understand it is a strict religious requirement for Jains. I’d be cautious about Indian restaurants in the city but the ones out in VA will 99% times accommodate Jain style properly.

If you go to an Indian restaurant in the city and ask them if they can make any dish Jain style, they will know what you are referring to. Most Indian restaurants are used to accommodating Jain versions of their dishes.

Outside of the city Herndon, Fairfax, reston etc have a lot of Indian restaurants and they can definitely accommodate Jain versions of their dishes.
