I am fortunate enough to live very close to Vinh Nghiem Pagoda and have tried the food several times there - I have brought friends along a few of those times and they all have enjoyed it as much as I do.
The restaurant is in the walls of the pagoda and it's usually quite busy in the evenings with locals; families, couples and monks enjoying the delicious food there. The staff have always been so kind to me and there's the sweetest little boy working there who comes up to me and always amazes me with his English.
I like the atmosphere there and I like the food even more. Portion sizes are huge; my friend and I ordered a tofu dish each, a 'side' of spinach and a serving of rice to share and it could easily have fed 4 people...we were stuffed! Actually, I didn't particularly like that tofu dish I ordered as I found the sauce a little too sour for my liking, but the spinach with garlic is good, and so are the 'fish' fingers, which taste really close to the real thing, as the tofu based 'fish' is wrapped in seaweed, giving it that slightly 'fishy' taste. Finally, I always get the fried sweet potato when I'm there - simple, but so good! Definitely check out Vinh Nghiem Pagoda restaurant, great selection of dishes and really pleasant surroundings!
