This is my favorite place to go for pho on the Eastside! Portions are huge, I always have to bring half of mine home for later. They have an extensive vegetarian/vegan menu available for those who'd prefer something other than pho. Square Lotus maintains two kitchens, one for their meat dishes and one for their vegetarian dishes so you never have to worry your food being prepared in dishes or oil that meat has been prepared in.
I have not been able to confirm with them that their faux meat is vegan. I had one waitress tell me that they make their own and another waiter tell me that they purchase it but he didn't know the brand. From looks alone, it looks like they use VegeFarm, which is carried in all of the local Asian markets. Most of what is carried is vegetarian, not vegan. Again, I do not know this for sure, it's a guess. Because of this, I only order dishes that use fresh tofu or vegetables only. I am allergic to eggs & whey which VegeFarms uses in many of their products so I cannot chance it. I will try to confirm this again the next time I go in.
