While Michael's isn't the best custard I've ever had (sorry - my fav isn't in Wisconsin)... it is quite good! I visited twice in one weekend and had a sundae and also a twister. Both were delicious though I think I might pick a sundae vs the twisters as it was a bit easier to eat...my twister had lots of marshmallow flavor which was nice but the sundae had an entire come covered in m&ms on it!
Service is a bit slow, but friendly and the treats were tasty.
Worth a visit if you're in the area.
