There are so many things to do depending on your likes.
A good place to start are sites like these (plus similar ones on FB if you're there), same with Wpg restaurants.

A cool website of totally FREE things in Winnipeg weekly, like free admissions to the Wpg. Police Museum, Mb. Sports Hall of Fame, Music in Parks and lots more is below. Check out all of the top menu tabs, as there's more than you might think on here with some digging. Neat site if you want to watch your budget, yet see some interesting things.
