In India, an alternative to dining out has emerged in recent years. These are called "Curry Points". (Perhaps they are called Delis in the US, I'm not sure)
See, Indian food is always a binary thing. As in, we eat a base item (Rice, pancakes like Dosa, Chapathi, etc) along with a curry. There are very few cuisines that consist of only one item. And most of them are from other countries. Examples are Noodles and Pizzas, etc.
So a staple Indian dinner is a bowl of rice, with two / three or more curries / gravys etc.
The "Curry Points" I have mentioned, simply sell the curries and gravies. They usually have about 20 different ones. People buy their choice, with each sachet costing about 10 - 20 rs ( 1 USD is about 80 Rs, so about 30 cents), go home, prepare rice or chapathis, which are very easy and quick to make, and have a decent dinner that does not cost an arm and a leg.
A decent dinner for 2 at a good restaurant in urban centers costs about 800 to 1000 (about 10 - 12 USD), but considering average household income in urban centers is about 40,000 Rs. (500 USD) per month , they are not suitable for daily visits.
A similar dinner for 2, with say 4 curries, costs about 2 USD. And that is including costs of rice / chapathis, energy costs, etc.
I don't know if this kind of model existd in the USA or European countries, but the businesses are very profitable. The store front is hardly 5 ft x 7 ft, costs about 4000 Rs. per month (about 50 USD Per month). Some store fronts are simply vans. Curries are prepared at homes and the storefronts are open for about 3 hours in the evening.
Perhaps this could be one answer to closing restaurants.
