Dieu Hien Quan: Authentic Vietnamese in Ansan If you are craving real Vietnamese food I suggest you head to Korea's multicultural city: Ansan (Subway Line 4). Because many of the large Korean firms have factories here, there is a large immigrant population. You'll be able to eat authentic Vietnamese, Thai, and Malayasian Food. You'll also see unusual food stuff for sale in the city such as Durian, cilantro, and basil. It's worth the trip. One of my favorite places to visit is Dieu Hien Quan because they have the best pho in all of Korea. Seriously, they do because the broth is the best and they add lots of fresh herbs like basil and cilantro. Dieu Hien Quan: Interior Shot Saigon Beer They have a selection of Vietnamese beers as well. I really like the Saigon Special Lager (the green bottle here). It had a very refreshing flavor. Click to read more for directions and for...frog legs.
