I know everyone is talking about best and good steaks, but I will share a bad steak experience that I had. Hopefully I can warn others to prevent them from making the same "misteak".
I went to the Wombles steakhouse in the Hobart Spar Centre in Bryanston. I ordered a 300g steak - not sure if it was sirloin or ribeye. I always order medium rare.
First, they didn't rest it enough, which I could tell by the pool of steak juices leaking onto my plate. I don't mind that when I braai at home, but at a flipping expensive restaurant like Wombles, I expected better. Second, the flavour just wasn't there. No browning or crust to speak of, just really underwhelming. It was like they had fried the steak and just served it to me sommer as soon as they thought it was done. For such an expensive restaurant, I was extremely unimpressed. I've had better steaks at Spur.
The best steak I've ever had was in Spain. Probably towards the North of Spain. Ordered a chuleton, which literally translates to large chop. But, beef in this case. Anyway, chuleton is a massive cut, I think from the rib portion of the animal, and I believe chuleton usually comes from old dairy cows. They serve it to you blue rare. They cook it on a hot griddle so that it has a nice crust, but the inside is very rare. And they sprinkled salt crystals on top. I was in heaven. Best steak I've ever had.
Woolies sells a similar cut of meat, but obviously not the same size and not from dairy cows. I can't remember what they call it. Its pretty good.
