Where can I find this in Queens?

My friend abroad with no access to Asian groceries asked me to bring her some of the Vietnamese seasoning in the pic for when we meet in September. I live in central Queens so I have no shortage of Asian markets nearby but haven't found it yet at the stores I frequent within walking distance. Before I make a trip somewhere I'd like to guarantee I will find this item. Any ideas of specific stores? I was thinking Elmhurst probably has Vietnamese stores that would have this.
