Is outback steakhouse a good steak house? it's like asking if KFC has good fried chicken or not.
It's a mass market steakhouse with the sole purpose of moving product at high rates. The cooks there often screw up your order by overcooking it. The lower quality meat usually means I would get it cooked more anyway, unlike a premium steakhouse with the dry aged beef, that I order rare, and enjoy the mustiness of the aged meat.
Is outback steakhouse horrible? No, as long as you go in with the correct expectations for the product, you'll be happy. When I go there, I sometimes will grab the A1 and occasionally dip a slice in it.
