Mortons Steak House, hands down the best!!!
I've eaten at Luegers, I've eaten at Ruths, Smith & Wolensky, Ben Bensons, etc... Mortons is the best in the business.
By the way, up on 57th street in Manhattan was Al's International Soup Kitchen. I used to get the soup a few times a week for years. Then he sold out and now there's an "Original Soup Man" popping up everywhere. The soups are supposedly the same recipies but anyone who had the 57th version knows immediately that the new version is only an expensive imitation.
That being said, the soup is still very good and worth trying out if you have the opportunity. It's just nothing like it used to be.
