What happened to Thick shakes?
When Thick Shake Factory launched, their shakes were so full of ice cream that they were undrinkable from a straw till 10-15 minutes after they were prepared. Now thick shakes are mostly water (Keventers) and lack flavour (Makers of Milkshakes) as well since almost everyone uses non flavoured ice cream and adds the required syrup flavour. I guess Thick Shake Factory still uses flavoured ice creams and Milkshake Mafia still prepares Thick Shakes that are undrinkable from a straw but there doesn't seem to be an outlet that does both.
