A few years ago I had a milk shake at a Steak and Shake that had ice chips in it (not ice crystals as if it been re-frozen, but lots of small chips.) It ended up tasting like "ice milk" I remember getting as a kid - very watered down. One of the worst shakes I have ever had. Based on all the positive comments here about Steak and Shake, that shake must have been an anomaly for the chain, so I guess I'll give them another try.
