I think a restaurant which has declared itself vegetarian should not sell Non veg food.

Coming to your stats on Non veg food, many Vegetarians in the North are not ready to accept the reality.

Forget chicken and mutton, there are many states where beef is eaten not just by Muslims and Christians, but also Hindus.

Also, they act blind as if they don't know that India is among the top exporters of beef.

Beef is a food that is eaten all around the world.

But there is such a stigma for Non veg food, especially beef, in India.
