When it comes to Steakhouses it will depend on how far you want to travel and if you want local or chain.
Let's start with Local
Downtown
Anton's Taproom - It is on the Trolley Route and is a butcher shop so you can order any size of cut you want. But I only found it to be ok.
The Majestic - I have heard nothing but fabulous things about this place. It is a true gem.
Golden Ox is back and greater than ever. Back in t he west bottoms.
Plaza
Stock Hill - great place of a once incredible Restaurant group that now has put all of it eggs in to this restaurant alone.
South KC and Overland Park
J Gilberts To be honest this has always been my favorite. It is great price and value and excellent food. Service it top notch and even though it is a chain it originates here.
Hereford House I know there are others in the city but I know of the OP one. I know the original downtown one is gone. It was the gold standard but that was long ago and has not been top notch for some time. Still worth a visit.
Jess and Jim's I will say I heard good things but the only time I went there was for the chicken which is something they are also known. But it is a casual and friendly place to enjoy a great steak without the stuffiness of some of the other stops.
Chains
