Wow! I love Avocado smoothie too! Luckily there's an Avocado tree outside where I live so I often make some for myself without going to the cafe =) but sure thing with a relaxing ambiance like that, such healthy smoothie will be more enjoyable. Never had Kale though, that's a new type of cabbage for me, I hope that's available in the shops here. My version is Avocado, carrots, moringa, banana and sweet ripe mango :-). If ever I find Kale, I might like to try it in place of moringa.
