Mae Varee sells sticky rice with mango from its storefront window. Mango sticky rice is naturally gluten-free and other than fresh produce, this is all they sell. It's served with warm sweetened coconut milk and crispy mung beans. I wasn't sure about the preparation for the mung beans so I did not sprinkle them over the mango. It's a bit more expensive than some street food but this was the best mango sticky rice I had in Bangkok.
