How is the public transportation in Minneapolis, MN? Any good?

I'm going to Minneapolis for two weeks for a business trip and have to share a company car. I've never been there and don't want to have to rent a car so I am hoping taxi/bus service is pretty good. I'm staying in Eagan and working in Burnsville and I imagine I'll be wanting to visit area Minneapolis/St. Paul and the Warehouse district. Thanks for your input!
