Although this restaurant may be completely booked on the weekend evening you are planning, and the prices are more than you would consider paying for your best winter coat, and you are not sure you like new wave cuisine, GO to this great restaurant. You will not regret it and will probably be mentioning it to all your friends for weeks to come. Grant Achatz was long the chef for Trio (in Evanston), and he has gained national attention for his food, deservedly so. The critics were tripping over themselves this past year to review this new place of his, and they weren't disappointed. And you won't be either. Bring a fat wallet.
