Tried the Italian beef place...we really liked it, but haven't been to Chicago, so don't know how authentic it is. I had it with no cheese, spicy jardinere, and dipped. Messy (of course) but very good, will have again.
Also had Bacchanal on Sunday night. Didn't get the text and after 2.5 hrs, the host let us in. Tough to make a comparison, because I'll get a buffet in Vegas about once a year, but I thought it was good and overpriced by like 10 bucks.
Finally, got dinner at Mon Ami Gabi and thought the service was great. We'd played golf and were still feeling the effects of Bacchanal from the night before, so we shared a couple of appetizers and sides (duck, scallops, green beans) and my wife had a salad while I had the oyster/potato chowder. With a bottle of wine, $122 felt like a cheap date in Vegas
ETA/OT: Played Asia Poker for the first time. Pretty fun. Pretty happy it's not available anywhere near where I am AFAIK.
