I was very underwhelmed with my experience at Milio's.
I stopped in over lunch while in Monona on a business trip. You can find it off Broadway next to Papa Murphy's. The place was busy, which is great for business. Unfortunately the staff didn't seem to be able to handle the lunch rush of customers. I ordered my sandwich and waited close to 10 minutes before it was ready. Need I mention this is supposed to be fast food?
I ordered a simple ham sandwich on wheat, #1 American Favorite on the menu. The bread was good and tasted fresh, but sadly that was the best part. There was more mayo and lettuce on the sandwich than meat and it was hard to eat.
Overall not a good experience.
