This is a bulletin board for Google Maps. I strongly doubt it is monitored by anyone who actually works for Old Chicago. If you have a comment or suggestion about their menu, I would encourage you to go to their corporate website and contact them directly.
It is a seasonal item. You may want to call them to see when they offer it.
It's a seasonal thing for them! So when the season goes for them they will bring it back! But this is for Google users to ask questions for others I would go to their website and comment there
