La Casa Mexican just opened opened in Pham Ngu Lao over a week ago. It is run by the same original owner of Margarita. Due to its location, the restaurant is quite packed though the Mexican food is pretty much the same quality as Margarita. The portions were a bit small, not really worth the price. Photos below:
