The question is what gave you happiness elsewhere?
I am not into clubs - and I am quite happy. I enjoy my Vietnamese friends and colleagues. I have been a volunteer with the local English clubs, acting as a resource - surprisingly I have usually been the only non-VN present. I study Vietnamese.
I don't know what the situation is in HCMC but there is a very nice cinema in Ha Noi that brings in very good movies, VN as well as foreign, old and new - there are also the larger commercial cinemas where you can see the latest and gratest stuff - western as well as Asian. There are bookstores (one English language bookstore).
