Salvadoreno #1- Pupusas - East Mesa

I ordered a plate to go and it was incomplete and tasted bad like something that was already ruined

Terrible service, the waitress who served me didn't know there was anything in the kitchen, it took more than 20 minutes to bring me my wrong order and then it takes 10 minutes and she tells me that they don't have what I ordered. I don't know if it's bad communication or the service is terrible. Also when paying they stole about 20 dll from us, which they put as a tip
