It’s legal, at least in some Michigan cities, to operate a bar out of your home. I need to do some more reading on this, but I wanted to share this video from three years ago about Frank’s Cafe in Wyandotte, MI.
There’s an article in a local newspapar about it as well. I remember seeing a bar like this on a business trip once, I think it might have been outside Baltimore, MD. That bar was in the basement of a house, but it had also been around for decades and had a lot of character.
Here’s an article on a few other house bars in Wyandotte: https://www.freep.com/picture-gallery/entertainment/dining/mark-kurlyandchik/2019/08/22/endangered-house-bars-wyandotte-chene-adele-gold-star-franks-cafe/2060889001/
