Ok, I've been giving the shakes a second chance.
I don't know if the cappuccino counts as a shake, but I love it, it tastes like a normal capp.
After trying all of the shakes again, with different things...
I find that the only one absolutely can't stomach is the strawberry. It tastes way too artificial.
And oddly, I usually love chocolate, but the choco shakes are very strange tasting.
I put vanilla extract in the vanilla shakes (and in the oatmeals), that helps a ton.
I'm trying to find a place here in montreal that sells different extracts, but so far no luck.. i'd like to try lavender, mint, etc.. all i can find here so far is vanilla and almond.
and the Davinci syrups everyone talks about are nowhere to be found here either.
So after giving all the mixes a try, the strawberry shakes and the tomato soup are the only ones i'll never eat again.
