to be honest, when i first came to visit hakata-maru ramen, i got lost. this inconspicuous restaurant is not visible from chatswood station and you would be lucky to notice it if you caught a bus from the bus interchange directly outside or opposite the restaurant....
this is probably one of the more authentic japanese restaurants that i have been to - pre-made ramen is stored inside a wooden box, waiting to be boiled and served to customers. even ryo's just stores their ramen in large plastic boxes outside their kitchen. also, their pork cutlets and karaage chicken appeared to be double-fried - i.e. pre-fried once beforehand, and left in a pile in front of the deep fryer until ordered, at which point the pork/chicken is deep-fried again to give it a crispy coating...
