Not likely to happen -- reservations for 10/29 were all made on 8/29. Odd improve slightly because it's a lunch.
Check OpenTable every so often in case someone cancels. Then call the day before in the afternoon and ask if there are any cancellations. Possibly check again in the morning around 10 or 11, but getting through the busy signals at that time will be very tough.
And have a table at a good back-up restaurant already reserved!
