The 16th Annual Chicago Restaurant Week is underway, featuring prix fixe menus for brunch, lunch and/or dinner at some of Chicago’s most well-known restaurants.

This year, 362 restaurants that are members of Choose Chicago, the organization that organizes the event, are participating. Despite being billed as a more affordable way for many to try a variety of restaurants, some eateries are adding surcharges that put a dent in the discounts touted by event organizers.
