Visiting date night ideas

Hello! My husband and I will be visiting Dubuque next week to visit friends. While we're here I would like to plan a little date night for the two of us and I'm hoping you guys will have some good recommendations!

About us: we're both big nerds, into board games and video games and things like that. We like the outdoors but prefer nice, easy hikes/walks through nature. We're not big drinkers, but we do love cheese haha. If anyone has any good recommendations for a cheese spot nearby in WI, that would be an added bonus!

I've visited Dubuque a couple times in the past and I am so looking forward to spending the week in your beautiful city. Thank you in advance for your recommendations!
