AuntyThong's smoothies are the best in Bangkok! Hidden down an alleyway, we walked past it on accident while taking a wrong turn, and I'm so happy we did. We ended coming back here almost everyday while in Bangkok because her smoothies are just THAT good. She also gives you fruit to snack on while you wait for your smoothie.
She doesn't speak a lot of English, but she's incredibly sweet and communicates easily with Google Translate. Make sure to stop by and try her mango smoothie - it's divine! And who knows, you might even spot our picture on her photo wall. :)
