Questions about Cleveland

Will be in Cleveland in about a month for the Shane Gillis show with my girlfriend and we will be staying at a hotel nearby the venue. Would it be safe for us to leave our car at the hotel and walk around downtown Cleveland? People have been telling us it’s a very dangerous city and my girlfriend has been getting a little nervous. Also is there anything else fun you recommend we do while we are there for the weekend? Any good restaurants or fun bars we should try? Or just something else going on nearby that same weekend we could look into.
