I'm going to be really basic here because my wife's family own this place and we've been accustomed to having these dishes for years. so here you go.
Larb with sticky rice (fave)
papaya salad
kow piek sen (noodles in a chicken ginger broth with blood) (fave)
pho
sai gob (laos sausage my fave)
also check the desserts out they are top notch laos/Thai desserts
lod chong
sangkaya
kanom chan
lomit
sakoo
one more thing if you see pork jerky on sale don't sleep on it is probably the best pork jerky I've ever had.
also this is a market as well and if you need to cook Asian you can pretty much find the ingredients you need here. happy eating guys
