Would any of your interesting items from your dinner menu be available for our lodge lunch group such as peking duck or possibly pork knuckle, etc?

For order like Peking duck and for group dinner, it's preferred to make reservation to facilitate the food preparation as well as to enrich your dinning experience

I had called in to them before and they said if you tive advance notice, they're more than happy to accommodate

If you call and give advance notice/reservation they will.

Just give them a little advance notice with a reservation

He definitively needs some advance notice.
