Truyền Ký - a small Hakka eatery in a tiny alley

I heard about this place long time ago but never had a chance to visit this famous small Chinese eatery in a typical tiny alley in Saigon. Truyền Ký, it's the name of this Chinese House. It seems we have several Truyền Ký in Saigon, but which one is the original, tough to say.
Judging by the number of guests having lunch today, the variety of dishes in the menu, I would say it could be one of the best. After the first visit, three weeks later I was back here with my other friends for dinner. Talking to the staff, I learnt that the business started back to 1950s, now managed by the third generation. The dish they serve is from the Hakka cuisine.

             We may never expect to find such a good eatery located in a tiny quiet residential alley...
