This was where Mike Myers, otherwise known as Austin Powers, received his formal -- and improvisational -- comic training. Over the years, the legendary Second City has nurtured the likes of John Candy, Dan Aykroyd, Bill Murray, Martin Short, Andrea Martin, and Eugene Levy. It continues to turn out talented young actors. The scenes are always funny and topical, though the outrageous post-show improvs usually get the biggest belly laughs. Next door is the Tim Simms Playhouse (tel. 416/343-0022), an intimate space that features fledgling local stand-up talent.
