Where the fuck is Henley.... oh Gladesville
Gladesville 42 is great in terms of customer service,but make sure to hit up Jessie on wechat and he will sort you out. This was my regular haunt but I'm without my car/bike atm due to rebuilds and its a little annoying via public transport.
Ginza and Ginza 278 are the other two shops I frequent the most as their customer service is also great and I have been going here for a long time and where I'm currently visiting due to proximity to my workplace/station.
