I was at Naha last night. I don't know if they have any more openings (I overheard that they were fully booked all week) but I posted their menu below. I had the risotto and it was wonderful. They also have 2 appetizers that seem to be vegetarian-friendly.
All menus are here: http://www.timeout.com/chicago/blog/o...

Most of the restaurants participating in Restaurant Week have a specific, limited menu available as part of the promotion. And those that don't already feature vegetarian item(s) on that menu will almost certainly be happy to make substitutions for vegetarians. However, the downside of this situation is, if those items aren't shown on their websites, and you don't want to leave yourself to their mercy ahead of time, you will need to call them and ask what they might have available for vegetarians as part of Restaurant Week.
Perhaps others here already know of, and can post about, what particular restaurants are doing. In any case, please let us know what you find out, too.
