Places like Kansas, Tucson (Buenos Aires Design Mall - see below) and I'm sure there are one or two more, have things like a BBQ sandwich and BBQ baby back ribs on the menu.
I think both places are not very good, Tucson being worse than Kansas, for BBQ (and most other things as well - not a fan of Tucson). Other places would be TGI Friday (Alto Palermo Shopping and Puerto Madero) and the Hard Rock (Buenos Aires Design Mall near the corner of Puerrydon and Libertador, can't remember the little street that hits Puerrydon where the mall is actually situated - behind the Recoleta Cemetary).
Hard Rock does pretty good ribs and they used to do a helluva pulled pork sandwich, but they've recently taken to cutting the pork in big chunks (I mean big chunks) and trying to make a sandwich out of that, not literally pulling the pork into strings. Hard Rock also has a BBQ beef, chicken and a mixed plate on the menu.
There's some other places that do ribs. Juana M (near 9 de Julio [really Carlos Peligrini] and Libertador, across from La Recova which goes under the freeway bridge) used to do them, don't know if they still do, and the only other place I know of that served BBQ ribs intermittently closed down.
I didn't even know of the place you linked, and I didn't know there were any BBQ places, committed to BBQ that is, in BA.
I make my own better, haven't sought them out
