You are making my mouth water. Morton's in Chicago, very memorable, but I just had some Kobi beef right here in Missouri a few weeks ago. Excellent.
I've heard about Morton's, but in two trips to Chicago never got a chance to go there.
On the West Coast, the must-go place in my memory is the Hitching Post, recently made famous in the movie Sideways, but it's been an institution for something like 100 years in its original location in Casmalia. That's the HP I frequented, but it burned years ago. The one in the movie is in Solvang, never been to that one, but have heard it's just as good.
A Hitching Post steak is worth a 100-mile detour to me.
