Is this just delivering a single Indian dish, in 3 variants, as a service (whatever that means in this context)?

Currently available alternatives:

1) go to the nearest Indian restaurant and get it fresh when you need it.

2) use a food delivery service and get if from your favorite Indian restaurant

3) use a frozen variant found in many grocery stores.

4) cook yourself, which is not hard, but we can ignore it in this context.

What is the difference/ unique value prop from the above options?
