We were a bit skittish to go look for this place as the reviews on Happy Cow said the address was debatable. We gave our taxi driver the name of the temple and the "no 5" address and he was sure there was no way we could have dinner there, but he turned out to be wrong, to his own surprise! The restaurant is at the back (or side? It was dark) of the temple, on the first floor. There was one waiter who spoke a tiny bit of English, and we speak some Mandarin so it worked out fine. The waiter also had some paper notes with English / Mandarin translations (not the whole menu, just some ingredients and dishes): very thoughtful. We ordered the sweet and sour "pork" and as we like spicy food the waiter recommended a dish with "sausage" and beansprout. We also ordered some dumplings. The "pork" was really tasty, crunchy on the outside and with a lovely sauce. The beansprout dish was lovely too: we loved the spices! The dumplings were okay. Some plain rice and 2 alcohol free beers made a great dinner. I would recommend you try this place!
Cons: no english menu, might be a little bit hard to find
