I order takeout from Soi a couple times a month and it is consistently delicious.
The garlicky morning glory greens are potentially the best item on the menu.
The yum gai zaap - little chicken bites fried and tossed in toasted rice powder and mint - is addictive. It's like popcorn chicken on steroids. I also love the pla tod nam pla, fried fish with a tangy and spicy sauce.
Service is always warm and they can usually have takeout orders ready within 15/20 mins.
