I really enjoyed ModernSteak We went as a group and mostly all had the Kobe Beef Hamburgers. Everyone enjoyed them. We had a lot of appetizers too, including onion strings (just ok), shrimp cocktail, fried shrimp, fries and we actually ordered a Kobe Beef Hotdog as an appetizer as well. It was very good came with all the Chicago trimmings on the side.
The decor is unique, not what I expected when you hear the name "ModernSteak". I was thinking something along the line of a Mastro's, Ocean Club or Mortons kind of vibe. None the less, the setting is eclectic and comfortable. We sat in one of the private dining rooms and the server was, friendly, very attentive and efficient.
Finally, the prices seemed reasonable for lunch.
The only drawback to ModernSteak is the parking (I know it was the Friday before Christmas). It is a pain to find a place to park at lunch.
