If you want Vietnamese hit 23rd & Classen officially known as The Asian District or Little Saigon.

Oklahoma City has a significant Vietnamese American business district and ethnic neighborhood located in the center part of the city. While it is officially known as Asian District by the city, due to the abundant Asian diversity of the neighborhood (similar in many respects to International District in Seattle), much of the original Little Saigon portion centers along Military Drive and NW 23rd Street between North Classen Boulevard and North Shartel Avenue.
