I've visited Chicago a few times and been wined and dined by my doting parents. But this trip, they won't be there to foot the bill. Where can I come close to Aigre Doux and Blackbird on a more moderate budget? Better yet, is there somewhere that's a steal for fine-ish dining that might be even more interesting?
I'm not talking super-trendy or hyper-hip, just something with a nighttime going-out feel and a bit of sophistication.
