I'm in the UK and know no one who would call McDonalds or Burger King a restaurant.

I wouldn't call TGIFriday a restaurant either.

What do you call them?

[LandR]

"Shit", mostly.

I actually can't think of a collective term that I would use for these places. If someone asked what a McDonalds was, I'd honestly probably reply "It's a fast food place that sells shitty burgers"

Yeah, they aren't restaurants, just places where people pay to sit and eat meals that are cooked and served on the premises.

The differences are the presence of a take-away option (which is as popular as the eat-there option), and that there's no waiter service. Nor cutlery.

Burger King and McDonald's are "fast food places".

TGI Fridays is a "chain restaurant" if we want to distinguish it from a "restaurant".

[DanBC]

take-away; fast food places; in a formal setting maybe fast-food restaurant but never restaurant alone.
