Try this:
We will not be seeing you at the restaurant we agreed to meet at later today. We have just had tremendous quantities of exotic meats and desserts at this brunch we just attended. Let’s instead, meet at our home at the appointed time where we will have copious amounts of rum. This will include one we just procured at a most unique liquor store we happened to stop at today.
I basically used the same words and order of entry you used. But you ran together a number of sentences that might have lost the reader in the middle of it. Try to write to the simplest capacity of the people you communicate with and don’t put so much information without a break for the reader to process it. It might get through better.
