Anyone who lives in, or around, Chicago might want to take a peek at this great map put together by Dr. Vino. According to him, the city has over 400 restaurants that allow customers to bring their own drinks to dinner, but even with so many places, it is hard to figure out quickly what restaurants permit this. The Chicago BYOB map is a start at cataloging all of these places so that diners know where they can - and can't - BYO. As of now, the map only lists about 45 or so places, but you can always write in and submit your favorite spots if they're not already listed.
And diners who are interested in BYO dining might want to check out the companion map of Chicago wine shops to pick up a bottle or two o the way to dinner.
