La Pampa Grill

I've been to Pampa grill last night. Being myself Argentinian I felt homesick and needed some good steak. My first impression was that the music was also salsa!... I love salsa but it has nothing to do with Argentina. Then the decoration didn't make any sense so I ask the waiter and he turned out to be Colombian and so the restaurant owners... I felt cheated but I carried on with my dinner.
I ordered an empanada, I received a Colombian empanada, one of those you normally have at La Bodeguita in Elephan & Castle with a weird sauce, it was nice though but not what I wanted. Then we wanted some bread but it had ran out so we were offered bread from the day before which was "still fresh".
Obviously, we refused it.
The Bife de Filete was fine, probably because it said it's brought especially from Argentina, who knows.
The last straw came when I asked for some chimichurri and they said the weird sauce was actually chimichurri...what??? I couldn't believe it. I don't think you have to be born and raised in the country you are cooking food from, but at least you must have some basic knowledge of its cousine
Service was poor and staff unsmiling yet quick.

Not coming back again, for £80 I can get something much better.
This restaurant lets Argentina down.
