Where do you go for Otaku Shopping

Marvin asks a very good question - where do you go to get your otaku goodies in your region?
In London I went to the Japan Center in Piccadilly or China Town and in Seattle I went to the Asian District.

Of course every Otaku would know that Akihabara as the place to go to when in Japan. however where are the places you go to in your area for your Otaku needs?
if you have an Otaku visitor, where would you take him/her?

in Manila the place to be at, for Otaku products is Greenhills Shopping Arcade in San Juan, there are a number of shops in V-Mall and Shoppesville. there are also decent eats around the area.

During my trip to Singapore, fellow otakus lead me to China Square Central. a grand place for otaku shopping.

how about your area? if your fellow otakus were go shopping in your area/country where should he/she go?
