hey hey.. HCMC is a very noisy and crazy place.. I would recommend the streetfood stret in District 4, and District one is never sleeping.. so just enjoy that madness.. :D

Thanks mate! Can I use Uber or any similar taxi rental app there?

Taxi is so cheap that there is no need for uber.. ;D

Well I use Uber mostly for convenience rather than price efficiency. In the last year in Malaysia I never used any taxi and never suggest anyone for the bad service offered from them.
