Chicago's Best Vegetarian and Vegan Restaurants
"Totally meat-free since 1983, The Chicago Diner has its menu packed with meat alternatives like seitan for staples like the deliciously spicy Thai chili wings and both black bean veggie and sweet potato-tofu patties that you can't miss. Don't forget to try one of its vegan milkshakes in many flavors from carrot cake to vanilla chai."
