Banana is my favourite, and chocolate is my least favourite (and i loooove chocolate milkshakes normally but the exante one isn't that good). I sometimes add a couple of drops of strawberry flavouring to my vanilla shake which makes it even better, but i like it on its own (it's not strictly allowed but i use the water based flavourings not the oil based ones, and 2 drops isn't gonna do much even if it's pure carbs, which it isn't hehe).
