Though it does serve meat, Your Choice is very vegan-friendly and the food is consistently delicious, above-average Thai cuisine.
The atmosphere is casual and the service warm and friendly. Quality is similar to Your Place on Milpas and Galanga on lower State Street, but these are all in different locations, so if you're on upper State, Your Choice is probably your best bet.
Their peanut sauce is especially good, so the Pra-Ram spinach is recommended.
Be sure to specify "no fish sauce," just to be safe. :-)Pros: Vegan-friendly, Consistently delicious
Cons: Serves meat, Not organic
