Sweet Willie-- if its not too much trouble, I would like to ask you some follow up questions... as after your comments and a lot of other feedback Ive read, I have decided to follow your advice and drop Charlie T's place and go for Trio.
Does Chef Grant Achatz work on Sundays....? I know its sometimes hard to know this for sure, but if you do have some inside info. it would be great. Excellent restaurants are just that when the head Chef is in.... and sometimes not all restaurants have a second fiddle that is up to the task. My ORD schedule this time around is a little complicated, so I have an only chance on Sunday to get a table.
Secondly, checking out the general information, I assume that the 5-9 hours of operation assumes that the last reservation for dinner is at 9pm...? Kindly confirm this.
Finally, do you know if the Tour de Force option is available on Sundays....?
Many thanks!!!
