I think Millions of Milkshakes is being literal with having millions of lists of milkshakes. Just after reading the menu I think I gained a kilo already. They have fruits, granolas, Milky Way, Skittles, Gummy bears, Nutella, Oreos and much more. I sudden had the urge to ask what's the 'healtiest' that they have and they recommended "Shake it Up". Without trusting my gut, it was super sweet and creamy (wondering why it should be the healtiest). I ordered the smallest but after I had it i think I just had a buffet dinner.
