I have been very disappointed over the past couple of years as it seems all my ex-favorite shakes (Dirty Martins, Players, P. Terry's) have gone from a dense, perfect shake to this new, frothy, airy almost marshmellow-y texture. Is it just me, or is there some new technology in milkshake machines that is changing the texture and density of shakes everywhere? Where is the best milkshake in Austin today? I am looking for milky-density, almost grainy with rich flavor... NOT too smooth, whipped or airy. Vanilla or chocolate only. I am on a quest, please help!
