Mastro's Steakhouse Chicago 520 N Dearborn St (312) 521-5100 http://www.mastrosrestaurants.com/ Let me start by saying that I have had many amazing steaks in my life from Morton's to the Chophouse to Delmonico's  in Vegas to everywhere in between all around the world.  The steaks at Mastro's were easily up there in my top 5 best steaks I have had and I loved everything about this place.  The main bar area is really cool and the actual bar is huge and had a very nice feel.  They were late seating us for our reservation would be my only complaint of the night and there lack of apologizing or making good on being seated so late that some of the higher end places like this would have done. We enjoyed a wide range of the menu and everything was fantastic,  we started with the Tuna Tare Tare, Steak Tare Tare and the crap stuffed mushroom caps and they were all very good.  For dinner 2 people had the 18oz bone in Filet and I tried both and they were cooked perfect and very great.  One person enjoyed the Bone in Kansas City Strip and it was outstanding also and I did the Rack of Lamb that was an enormous full rack of 8 full super huge shanks and they were by far the best I have ever had.  We enjoyed a couple sides with our meal,  the famous Lobster Mash was outstanding and the brussel sprouts were good but a little too hard. Great great meal all around from the service to the wine list and all the food was amazing.  I will definitely be going back and I need to remember that this place is pretty pricey but the portions and the quality and taste make it all worth it.
