A precious spot for Toronto's comedy community, Bad Dog is a great place to go to check out a show, try your hand at comedy, or take classes in improv or stand up. I've never attended classes at Bad Dog, but I have had the pleasure of attending several comedy shows, and they have always been a fun time.
With a rotating lineup of new and regular themed improv shows, any given night of the week will find you an inexpensive and fun night out at Bad Dog. I always recommend people switch things up from the usual dinner/drinks/movie circuit and take a date out to a comedy show here. I also suggest you check out shows first if you're thinking of taking classes, too.
I find that it's really easy to get locked in a cycle of the same nights out at the same pubs and restaurants, but one of the brilliant things about comedy shows at Bad Dog is not only are they cheap but as they are mostly improvised you can go to the same show and experience an entirely different performance every time. If you haven't dipped your toes into the comedy scene, Bad Dog is a fun and friendly first try.
