It is a large indoor market, set in a warehouse, Hmong stores and stalls only, a kind of Eden Center (for those of you who know Falls Church, VA) for Laotians. The produce and spice and bark sections are amazing. Along one wall of the warehouse are about fifteen small restaurants, barely more than stalls, mostly Hmong in their cooking but two served authentic-looking Thai food.
Based on visual inspection of the options, we dined at Houaphanh Kitchen, which was superb, don’t forget the dipping sauces. And I hope you like purple sticky rice. The other places did not look much worse and there were many more dishes I wanted to sample. Overall entrees ran in the $4 to $6 range. Highly recommended.
