I was again looking for Tamiya paints and heard about this place at Yonge & Bloor. I found it on the ground floor of the mall and it turned out to be a plain old toy store, but when I asked an employee about paints he said the grownup toys were downstairs in their other store. Go back towards Yonge, go down the escalator, and it's right there.
And there it was, with lots of model kits, board games, miniatures, and a huuuuge selection of paints. I got what I wanted and got out, but I really need to spend more time looking around in there.
