Visited Chicago...Stayed at The Drake...Ran the Lake. Found this place. I was impressed. L'appetito is sort of underneath Michigan ave, yet has an outdoor patio as well as a seating area inside the restaurant.
I had the Italian ice around 12 and a Vegetarian sandwich at about 4:22. Both were excellent and relatively inexpensive.
I probably will not fly to Chicago to eat at L'appetito, but if I lived there, I would probably be a regular.
