Agreed. From the Dick's website:
Dick's shakes are made the old fashioned way: You won't find any machine-made shakes at Dick's. Our shakes are hand-dipped and individually whipped the old fashioned way for truly smooth texture that you just can't get out of a machine.
The shakes are indeed wonderful.
Regarding trans-fats, I'm particularly worried about the fries and the burgers, which have a distinctive taste that makes me keep coming back decade after decade.
It would destroy the entire Dick's Experience if that flavor were to change.
