I am surprised that there hasn't been a review in this thread for over a year - but the comments above were good preparation for us to use a Groupon last night for our 26th wedding anniversary dinner.
We were treated to the five course tasting menu, and with the discount, it was a reasonable value. I cannot, in good faith, say that I would have been willing to pay full price for the same meal. But on the whole, the menu was cleverly designed and well executed, and several of the courses were excellent.
An amuse of a pyramid of carrot gelee' was tasty, and creative. Our first course was a decomposed beet salad, featuring Indian spices (brussels sprouts roasted with garam masala, and pieces of papadums) and citrus, and house cured gravlax. I was impressed, the thoughtful presentation allowed for creative flavor combinations; this was well executed, and fun to eat.
Our second course was an outstanding presentation of a perfectly seared scallop served with oxtails, with essence of sweet peas, actual sweet peas, and carrots. This was also a well executed dish, the scallop clearly fresh, and perfectly done.
The third course was a dual entree - a medium rare slice of roasted, well aged filet mignon, combined with braised beef short ribs served with truffle foam, and a really nice potato/mushroom "lasagna." This was the only disappointment of the evening, as the short ribs simply lacked any flavor whatsoever. The filet was good, and the potato/mushroom dish supplied needed flavors to the other items. And for the record, I did not subtract any points for the truffle foam - although if I dined another 10 years without a foam on a savory dish, it would make me very happy.
Fourth course was a palate cleanser, a white peach/lemon sorbet, served with a tokay soup; this was beautifully flavored, well composed, and made for a nice transition from savory to sweet.
The dessert course also was dual; with a small butter pastry apple tart accompanied by goldschlager ice cream, and a steamed chocolate cake accompanied by armagnac ice cream and brandied cherries. This also was a hit, well flavored, and executed with a steady hand.
We left the restaurant impressed, chef Taus has a creative sensibility, and the execution was almost flawless. Service was impeccable, pacing was good, and the quality of service did not decline as the room filled during the evening.
Now the key question... would I return? Not without some form of discount. On the other hand, I left feeling that there were four hits out of five courses, and that was better performance that I have seen from several other high-end Chicago restaurants.
