If you want to go for vegi food in Hue, you would probably have two major options: Lien Hoa and Thien Tam. There are of course more vegi restaurants (for instance Bode on Le Loi, but I do not recommend it).
Lien Hoa is located within downtown, near the stadium. So the accessibility is good for those who does not travel too far to eat. This restaurant has been famous among locals for a quite long time, and recently expanded to accommodate more customers - so you see how many locals like this restaurant. The food at this restaurant has stronger and saltier taste as compared to other vegi restaurants in Hue. If you prefer lighter taste, Thien Tam would be better option for you. In terms of space, Lien Hoa is more congested with less space between tables. Everything is pretty good, but go for hot pot, fried rice, fried tofu, etc. that are standards at this restaurant.
Thien Tam is located outside downtown, some 10-15 min taxi ride from the city center. As it is located outside the city center, it has a lot of space with some nice gardens and provides half open-air atmosphere, where you can relax and eat. This is relatively new restaurant, but it was filled soon after its opening because of its atmosphere and good quality of food. The food here is much lighter as compared to Lien Hoa. If you prefer punchy flavor, Lien Hoa would be better option for you. Go for some local dishes such as banh beo, banh nam, nem lui etc. that are usually not vegi dishes, but here, they prepare it with 100% vegi of course. They also have wide variety of dishes on the menu. Weekend lunch is also relaxing and pretty nice here.
