I passed this by whilst out for a stroll and dragged back our folks for Vietnamese to try it out.
Firstly the prices are criminal, how can you get this much quality food for so little? Secondly the food is amazing, very fresh, very healthy, everyone really enjoyed it and it was fun to try something completely new. Lots of meat and vegetable / salad dishes with rice or noodles many soup or salad bowl based and very generous portions, good selection of beers too.
Service was a bit odd to start until we realised that you have to do a bit of self help by ordering at the till and paying first but once the concept was grasped all was good and our host was very hospitable and friendly. A good evening out.
