Offering at least one option that don't include factory farmed food, that caused a lot of animal suffering in it's production, should be the bare minimum.

"When I specifically go to a restaurant run by animal lovers and I can't even get any dead animals from them, you shouldn't be able to get food that didn't harm animals in any restaurant!"

Wow. I guess there really are people who want to make it even harder to avoid causing cruelty, for no reason... Just why?
