It looks as though the Cactus Pit is going to become a CAU restaurant. (Planning application was here, but won’t load for me currently). They specialise in Argentinian beef according to their restaurant website, which mentions other branches in Cambridge and Guildford.
So thirty seconds walk from a lovely Argentinian beef restaurant, Blackheath residents are going to have a second one. I really hope it doesn’t damage Buenos Aires, as its probably the nicest restaurant in the village (even for vegetarians).
(Thanks to the anonymous bugler who spotted the application). Image above shows the CAU restaurant in Guildford.
