...and "Street Food" would also be "fast food" in many places, especially outside of the USA - and lots of very tasty food to be had too, and often cheaper than what it would cost if one were to make it at home. And they could be pretty nutritious too. :-) Lots of eG folks would seek out this type of "fast food" in, say, SE Asia. ;-) Even in the USA - what about Food Trucks? Taco trucks or carts? (Hot dog carts certainly are fast food vendors too) The abuelita selling wonderful cubanos or medianoches, say, from her cart? They all qualify as "fast food" too, even if they may not be quite "restaurants". Chinese Takeout places would qualify as "fast food restaurants", I would say.
