In three weeks I will be attending a conference at the Marriott downtown Mag Mile. We have a budge of $25 a day for food. We are all teachers. Any CHEAP suggestions for restaurants/café for the three days we will stay there. I like mainly American Style dining (pizza, sandwiches, breakfast fare, pasta, pastry) not a fan of sea food or spicy food. We will not have a car and in most cases fairly limited time for meals. Any and all suggestions greatly appreciated.
