"Churrasqueria" is the most "River Plate"thing, right after "Tango" and the Argentinians as we use it (Churrasco") to refer to a steak.
The Steakhouses in Argentina and in Brazil (specially in the Rio Grade do Sul region ) are called so, with the only ecxeption is Uruguay where we call it "Chiveteria" I know that sometimes In the US they "sell" you something what Isn't really so or not from that country at least.
About the meat (I guess in the US since they have other Meat aviable it is more tastier than in Brazil itself) In Rio Grande do Sul like in Urug. and in Arg.they mostly use Pampa or Hereford, more to the north it is Zebu (not so Juicy and tasty).
Edit: Churrasqueria , Chiviteria or Parillada, most comon (for Steakhouses)
