I have recently enjoyed two restaurants in Dallas, both of which are fully vegan - and know of others from past years living out this way.
The first recommend I have is: BLISS Raw cafe, which is located at 6005 Berkshire Ln, in Dallas, TX. That's a side street just south of NW Hwy between Preston and Dalls Parkway. They are open Mon-Sat, beginning at 11am, and I believe they close around 9:30 at night; Sundays are from 11 am to 4 pm. I HIGHLY recommend their coconut kale enchiladas!
Next up: Loving Hut ~ 14925 Midway Rd, Suite 102, in Addison, TX. Healthy, natural, green - all vegan menu, mostly cooked Asian fare, but they so have some amazing salads on their menu as well. They have a lunch buffet Mon-Fri 11am - 3pm, but otherwise are open 11am - 9pm Mon-Saturday.
Now from years past:
In Richardson, are Veggie Garden & Suma Veggie cafes - also Asian fare:)
Then there's Spiral Diner - originally in Ft. Worth, and also is in Oak Cliff - all vegan all the time - always amazing and never boring! Cuisine from one end of the spectrum to the other:)
Some I have not checked out yet: Cafe Elite, D'Vegan, New Start Veggie Garden, VSPOT Cafe, and Zombie's Food truck (Ft W).
Then for Vegan friendly - you CANNOT miss - Kalachandji's Palace!!!! This is our local Hare Krishna temple in SE Dallas at Gurley & Grand off I-30 near Fair Park. This is a buffet and they are always great about designating what is vegan and what is lacto-veg. Ho for kirtan - the drumming and dancing is wonderful :)
