I've not tried them myself cos everyone seems to hate them on here! My advice would be to ask for a sample one (which they should happily give you) then, if you like it, you can go back and swap for some of your shakes. If you don't like it and can't finish it then you won't have missed out on a precious meal!
They are absoultely rotten , i had a bite of coconut one yesterday and couldnt eat anymore. bought 7 of them so i'll just take them back and get them changed. xx
