You should. It's manga fan's heaven with all kinds of older manga books that are reasonably-priced! Some of the employees work in cosplay costumes as well. I once took a young American lady there and she literally cried in joy when she found a manga she had been looking for for many years.

After Mandarake, you can go to Dairy Chico on the basement floor for the tallest soft-cream in Japan!

This one isn't even the tallest that they serve!

Store Information | MANDARAKE

Probably my favorite store in Japan...

I love manga myself, but didn't know of this place... how much would a typical manga cost there?

Wow :D I'll probably go to the one in Akihabara
Can't wait!!
