Bike shop recommendations? Seoul & Tokyo

I'm lucky enough to be going to Seoul & Tokyo next week for work & was hoping some helpful forumers might have some up to date advice on bike shops to visit? So far my list consists of:

1.W-Base (Tokyo)

Any info would be much appreciated.

Thanks!

Punch Cycles in Asakusa, Tokyo is alright. It's tiny and the owner doesn't speak much English. He didn't seem too pleased to see me. Full of amazing NJS frames though, despite how small most of them were.

WBASE in Harajuku is quite cool. There's loads of crazy stuff (and people) to check out in the area too.

Went to one branch of 'Y's Road'. Felt a lot like Cycle surgery or evans. Some bargins to had on reduced lycra, if you can find your size.

Can't help you with bike shops - I've almost never seen anyone cycling in Seoul, which once you've seen how they drive is not surprising.

But....go and eat here - amazing, smoked / steamed duck. Delicious and impossible to find outside Korea. Address is approximate (finding anywhere in Seoul is a pain in the arse) but it's in a side street, just opposite the central bank going into Namdaemun market. There a picture of a duck outside and it's normally packed.

Other bits of the city to explore - Hongkik, Itaewon, Sinsa-dong and Gangnam.

Great, thanks both- I have absolutely no idea about anything as it's my first time in both cities, so your advice is priceless!

There's a few guides for watching/betting on Keirin about on the internet. There's quite a few velodroms not far out of Tokyo. Some do night races too.

It's good fun, but don't expect anyone to speak anything above a very basic level of English.

Cool- I'll defo do some extra googling on that- Kerin would be awesome! Think I'm gonna be pushed just to get to some shops, let alone to the track as I'm working, however I'm planning on attempting to fit in as much as possible- there'll be time to sleep when I get back!
