Directions:
If you are in Roxas Blvd., in Luneta, coming from the south, go straight northwards until you hit a rotonda.
Turn left on the rotonda.
After about 50 meters, you will get to the surplus stalls. Ask where little Chatty's is. There are more surplus stores for japanese audio after Little Chatty's.
