"Union Square has many vegan options, but be prepared to have your mind blown by Littleburg, a takeout-only Mediterranean place sandwiched between Backbar and Bronwyn. The all-vegan menu rotates, but may include such crowd-pleasers as a seitan gyro, a pambazo sandwich with shiitake mushrooms, sujuk-roasted cauliflower and delicata squash, and almond tzatziki on a roll grilled in urfa salsa, and pita with yuba shawarma." - Valerie Li Stack
