First week (through the 9th) is Jersey Week and the Food and Wine festival ends on 9 Nov. It's not crazy busy, but yes, you will need ADR's. We always go in Nov, mostly the first couple of weeks and we have seen people turned away at Sci Fi, Crystal Palace, Le Cellier, 50's PT and a few others. You should assume you need ADR's anytime of the year. Or you can risk it and not get angry or upset when you can't get in somewhere.
