The people of Hue have a strong tradition of eating vegetarian food, so vegetarian restaurants are more common in Hue than in the rest of Vietnam. On the 1st and 15th of every lunar month, vegetarian restaurants are packed full of patrons for dinner and it may prove difficult to find a seat. Vegetarian restaurants are the cheapest places to eat, after street vendors.
Thanh Lien Quan Chay
At 52 Nguyen Cong Tru street. Delicious and cheap buddhist family restaurant, very friendly staff, easy to miss from the street, look for a sign with TATA. Rice with vegetables, tofu and other delicious morsels: $0.50. 4-person hot pot: $2.
Bo De
At Le Loi street and run by the Huong Giang travel company. Extremely popular with locals. Serves delicious vegetarian appetizers and entrees. Expect to fill yourself for US$2-3/person. While the restaurant serves truly wonderful cheap vegetarian dishes, for some reason the staff is very unfriendly with foreigners. Half of the dishes listed on the menu are not available.
Lien Hoa
At Le Quy Don street. In the grounds of the Lien Hoa pagoda, across from the football stadium. Monks and nuns frequent this restaurant during lunch. A small shop near the door sells Vietnamese language Buddhist texts, prayer beads and icons.
Com Chay (vegetarian rice)
It Is near the River on on the 'newer side' it has simple, but good and cheap vegetarian meals.
Tinh Tam (or "calm soul")
It is located at 12 Chu Van An street. Answering the question "Who would Buddha rip off?", this Buddhist restaurant in the backpacker district has a little scam going. There are two menus- an English one with strange dishes at high prices, and a Vietnamese one with normal Vietnamese dishes at normal prices. If you try to order off the Vietnamese menu, the owner will claim those dishes are not available. If you do succeed in ordering a Vietnamese dish, the owner will bring out an unidentifiable dish and claim it is what you ordered (going so far as to claim a plate of noodles and tomatoes was "pho") at 4-5 times the price. If you complain, the owner suddenly doesn't speak English. You can find plenty of unhappy customer reviews on the internet of this place. To avoid. Price: Vietnamese: 5000d / Other races: 40,000-50,000d.
Quang Tinh
At 91 Vo Thi Sau street , in the backpacker area, open from 6am to 10pm. Very simple place, menu of noodles, rice, and so on, starting at 10,000d. Also sells cigarettes and hard alcohol.
