Basically. Imagine an ice cream truck, but with some rice cookers and curries going in the back, playing Bollywood music, and driving a route in the suburbs. Plus an app estimating time until arrival, taking orders, etc.

There was an Indian restaurant near my office that was almost always empty - good people and decent food, but they never did anything to try and stand out. They've disappeared now. Were I in their shoes, I would've been trying something like this on the side for sure.
