I've heard a ton about Mickies since I've moved to Madison, and I'm glad i finally got to try it out! It's an old-styled diner, and fairly cheap for the huge portions. I highly recommend trying out the Scrambler, which is basically just a huge mixed portion of breakfast foods. I've never seen anything like it before in any brunch diner, so that was really unique! I personally got French Toast topped with strawberries, which was delicious!
It's always pretty busy - I went at 11 AM on a pretty snowy day, and I got one of the last booths available. I would always expect a bit of a wait if you're going around brunch time, but I think it's well worth it. Perhaps with a few more visits, I would be able to put this at 5 stars!
Finally, I've heard their shakes are amazing, so I would certainly try them out if you're a fan of shakes! Would definitely recommend trying it out if you're in town and want a quick brunch!
