It could be just a filter, along with dietary requirements. In this way the one webpage can be made to work for everyone.

Honestly, although fast food is normalised in America, there are lots of people that would never be seen dead, chomping into an American burger with fluorescent beverage, to consider it 'food'. Do they even have vegetables in these places?

Also, cooking is not what some Americans do, whereas some people outside America cook from scratch every day. These visitors need to know dining options, which can mean eating out or finding somewhere with ingredients that are not overly American.

America developed differently to the rest of the world regarding food, an app is needed to help tourists find something vaguely edible rather than utterly soul destroying.

Vegetables, salads are usually more expensive compare to burgers and pizzas in US. I think people gotten used to this fact. I can see why people outside can get shocked by how things are here. Don't blame you for a bit.

When I travel abroad, I am usually shocked how good food are compare to how much it cost, especially in Asian Countries. European countries, I get shocked at both good food quality and price haha
