It's rare, in America, for there to be an actual stall. Food trucks or carts are much more common and serve the same function. Stalls can be found at festivals and fairs.

Some of the best food comes out of food trucks. There's a whole little culture around food trucks.

I've seen stalls in other countries on TV. Anthony Bourdain, for instance. He seems to accept a certain amount of food poisoning and dubious ingredients. Some of it still looks really good.

We also have the Tamale Lady phenomenon here. If you see a Hispanic lady or old man selling tamales out of a cooler, you better get some. They'll be the best damn tamales you've ever had.

We try and only eat out as a treat. Almost all of our my meals are eaten at home as we work from home these days. Also, my wife is an amazing cook and her food is better than most restaurants. We usually have leftovers or a sandwich for lunch.

I'm not familiar with your currency symbol? What country do you live in and are the health standards low enough that eating from a stall is a concern? That's a different situation.

I'm in the US, so food trucks, stalls and gas stations actually have decent standards. (Often, the cleanliness in these places is heads and shoulders above corporate chain places.)

I learned to always check the bathroom of a restaurant. How clean they keep their bathroom tells you a lot about how they keep their kitchen. Small, family run, places tend to have the best food and the cleanest bathrooms, in my experience.
