On my most recent visit to Chicago two weeks ago I took advantage of the wealth of info on this board, had one great dinner and one not so great.
The good news: Chilpancingo. Wonderful dinner. The obligatory margarita was very good, but not the best I'v had. Started with a ceviche appetizer on crispy tortilla slices. Delicious! Portion was enough for two to split without skimping. Entree was roasted quail in a red chile mole sauce. This sauce was one of the most memorable I have ever enjoyed, in any cuisine. My only complaint was that one quail was not enough. The bird was about the size of a parakeet with a total of maybe 5 good bites of meat, and I had to work to get those. I understand that quail is an expensive item, and restaurants often only serve one, but still. It was accompanied by pureed pumpkin, wonderfully seasoned, and delicious. Service was attentive but not intrusive. The room is very pretty, but also somewhat large, so this is not a place for an intimate dining experience. All in all, a great dinner. Thanks to this Board for clueing me in.
Not so good news: Hugo's Frog Bar. Near my hotel, so I gave it a try. Noisy, crowded. I had the boulliabaise. Normally a dish I enjoy, but this was a few mouthfuls of fish, accompanied by some overcooked clams, mussels, and shrimp, swimming in an ocean of mildly flavorful broth. I didn't read anything about this place on the Board, so I should have known better. Addendum: Had a lunch at Gold Coast Dogs in the Loop. Charred dogs were ok, but (sorry) don't compare to the temples of dog in NYC, where I grew up.
Looking forward to my next visit!
