We went to the new Tom Colicchio's Heritage Steak in The Mirage and had an amazing meal. The service was impeccable--some of the best I've ever had. Our appetizers, bone marrow with lobster and corn and the pork/foie gras terrine was spectacular. Our heritage steaks and sides (particularly the creamless cream corn) were fantastic. Amazing cocktails and an excellent wine list. Our dessert of peach gillette with peach ice cream was heavenly.
Our biggest complaint? The acoustics. The restaurant is in the "jungle" dome in the entry of The Mirage and the noise, sound intrusion, echoey background music really ruined an atmosphere that was practically perfect.
