I use a forman, it cooks similar to a skillet except it drains, it produces less smoke than a skillet for this reason. It does not taste like an outside grill. Nothing compares to that smoke you can create outside. The forman gets typical grilled food (steaks, shrimp, dogs, burgers etc) cooked, but not "grilled" like you would expect, furthermore, I would not recommend cooking any steak on an indoor grill. Id probably rather cook my steak in a skillet than my forman after trying that a few times, but for steak and seafood I just go outside
The forman is good for burgers, dogs, chicken and sausage tho.
