So I have a haven't-seen-them-in-forever friend facing a 5:30-9:30AM layover at O'hare on Sunday--and I agreed to grab a bite with her while she passes the time. Curious question, then: what would be the "best" restaurant open at 6AM on a Sunday? Apologies for the air quotes, but I am particularly open to non-breakfast places; my first thought, in fact, was that Lebanese place on Lawrence that Sula reviewed in the Reader a month or two ago. Any leads on restaurants open in Chinatown at this hour, or a taqueria that serves up a consistently reliable taco at all hours? That sort of thing. I would prefer something other than a dreary diner--dialing up the "way-back machine" is depressing enough to begin with--but a good breakfast place (i.e., one worth driving to) would certainly suffice.
Have car, willing to travel--say, South Loop at the farthest.
