What to do for a chill rainy afternoon?

I’m flying into O’Hare around 3pm this Saturday (supposed to be rainy) and I’m checking into my hotel near 360 and have the whole afternoon to myself. I’ve visited Chicago my whole life so no touristy things. Looking for a chill coffee shop vibe, maybe something with a view? Or just other fun things to do. Bonus points if you can find some yummy dairy-free food/drinks! 🤟🏼
