I came here after a few recommendations from friends. I thought the pho was good but not the best in Adelaide. The laksa noodle soup is very good.
Their servings of Pho are huge! I wouldn't necessarily recommend traipsing all the way out to Arndale to try Khang's Pho, but my sister had a Laksa that was out of this world. The pho was a good, solid effort, and something I'd be happy to eat again. We were surprised to find such a good, solid restaurant in such an odd location, but obviously a lot of people know how good the food is here - the place was fairly full on a sunday evening at around 9, just before they shut (we were looking for food after we watched a movie in the shopping centre).
I can definitely recommend this restaurant if you're in the area!
