Le Cellier offers lunch packages only. Dinner is a signature meal (therefore it's already higher cost or two DDP credits). I think they didn't want to charge more than two DDP credits and there was no sense in charging two for the CP extras when it already cost two (which would mean DDP guests would get the CP extras for basically nothing) or coming up with an additional price tier to cover a signature dinner.
Unfortunately, with a lunch package you're limited to the 5 PM show.
