$10 isn't $10 everywhere. There are still places in the country where $10 feels expensive. You may want to add a filter for even cheaper meals.

On the other end, increasingly, even fast food combos are more than $10. It would be helpful to highlight franchise meals that are actually affordable. Just don't let people add dollar menus or non-combos.

Posts should somehow only admit whole meals. If someone says their local taco truck sells a single street taco for $6.99, that's means a meal is more like $20.
