Although I'm not a comic book aficionado, I'd have to say Silver Snail is a super hero mecca. Unlike other comic book stores I've visited, this place is kept in immaculate order - clear plastic drawers house thousands of plastic covered comics all labeled and filed accordingly.
There are tons and tons of super hero, nintendo and movie figurines laid out all over the store, many of which include signs that read "do not touch!". It was especially hard for me not to feel the creepy exterior of the LIFE SIZE alien head from the alien movies. They also have a huge selection of movie memorabilia, graphic novels (my boyfriend picked up The Watchmen, which I am dying to read!) and anything else a nerd in Toronto could possibly ask for.
I've also been told by many a comic book lover that their prices are very competitive and their selection is outstanding. So for all of you looking for some super hero lovin' in your life, Silver Snail will treat you right.
