No personal vendetta on my part about Cabana Las Lilas. I've been there a couple of times and it's a pleasant place with reasonable food. But its overpriced and you are surrounded exclusively by North Americans overpaying for their steaks. I can do that in Toronto.

Never tried La Brigada but I would highly recommend La Cabrera in Palermo. It's also aimed a bit at tourists but there will be lots of Argentines among the clientele, the steaks are fabulous and the value is excellent.
