I visited XO Bistro on the advice of my brother, who says the vegan pho is excellent. It was. What made the soup was the broth, which is a true vegan broth but has much more flavour than other ones I have encountered. I ordered the small size, which was ample enough for lunch and slightly more expensive than Chinatown (not a surprise, given the location and upscale interior). I especially liked the tofu, which was fried but firm. Definitely deserving of a repeat visit.
