I've been sayiing for a long time Phoenix needs a broader diversity of ethnic restaurants beyond the standards. Enter Sekong By Night. This quaint little place tucked on the north side of Indian School is well worth the visit, despite the difficulty you will likely have in finding it.
While culinarily similar to the likes of Thai and Vietnamese food, it is different enough to stand on its own. There are standard spring rolls, but then you can get into the meat dishes and this pancake/crepe thing that is my new favorite. I'm excited for it to cool down just a bit here so I can justify eating more of their soups, of which they have many.
It's run by this young guy who is incredibly nice and is more than willing to give my girlfriend and I some advice on our hopeful and potential travels to the region. I think his mom is the chef, which makes this a great "mom and pop" (mom and son, really) place worth the trek from any point in the valley.
