Fast food chains for vegans and vegetarians

Dining out as a vegan or vegetarian isn't easy, a lot of restaurants don't have options for vegans or vegetarians and even some of the one's that do don't have that many options. I'm not saying we should stop eating meat, that's your business if you still want to eat meat and it shouldn't be illegal to do that. But I'm asking to have more restaurants specifically for vegans and vegetarians (or to have restaurants serve more vegan options) and to have some ice-cream parlors like the one's that serve the four flavors of chocolate, vanilla, twist, and the cones dipped in chocolate the are entirely vegan.
