7 Floors as well for the one in Ikebukuro.
But I think it is smaller, so the stuff are more packed together, but somehow I like to go to that one more. (More familiar to me maybe) But if you want to buy stuff, both location pretty much have the exact same thing.
The other stores next to it are ok, small and packed but I never bought any item from there.
