I think your plan looks really good.
A couple of thoughts/comments.
I hope you enjoy M.Henry...never had a bad brunch or lunch there.
I really like Alex's suggestion of Big & Little's, and would choose it over Bari's. We used to order takeout from Bari's for work, was a welcome relief from some of the usual catered lunch fare, but not sure it beats Big & Little's.
Save some room if you are heading over to Hot Chocolate...combining it with Takashi is a good one-two punch.
Another thought it to check out our food truck scene. Meaty Balls is a good one for lunch, and they post online and their twitter where they will be.
Also, I was skimming through this and didn't notice when you are visiting, but you may want to think about getting into Next. You could try same day tickets, especially if you are flexible with some of your reservations (e.g., Sunday at Avec you aren't going to make reservations). Last I saw the Thai menu is going on until Oct. 9 and the Childhood menu is starting the following week. If you are coming after the Thai menu ends, you could try to get tickets when Childhood goes on sale and turn into a crazy person like the rest of us.
(Just don't turn into one of the idiots that gets mad at Grant and Nick for "forcing" them to sit in front of their computer, or miss meetings or their commuter trains all day trying to get tickets.)
