Not to be a purist or a snob, but I feel like in any major city, it's a cryin' shame to visit the Borders Starbucks. The B Pig Cafe was a good example of a neat little small coffee shop.
As long as we're downtown, how about something touristy, like visiting the Bean? An xkcd meetup at Millennium Park would be neat.
Otherwise, I humbly suggest Allende, the best mexican in the world, which is only 5 minute walk from the Red line Fullerton stop, Shine Garden, which is fantastic sushi and only 2 minute walk from the Brown line Armitage stop, or the Billy Goat Tavern on lower Wacker, maybe 9 minute walk from the Red line Chicago stop.
-I know this: if life is illusion, then I am no less an illusion, and being thus, the illusion is real to me. I live, I burn with life, I love, I slay, and am content.
