Update 18 October - please note Annie will be making her veg*n Sunday lunches effectively as a booking for us - see below - so if circumstances change please update your reply. I will need to confirm numbers with her before we go.
I went to the Navigation this Sunday (16th) and found that Annie had temporarily put a hold on doing the Sunday lunches - the recent warm weather had they believed resulted in a low demand. However, I spoke with Annie and she agreed to reinstate them for our visit on Sunday 30 October.
Based on the poll the most popular day was Sunday 30. I would suggest a light breakfast or you will struggle to eat all of the veg*n Sunday lunch and sweet. Veg*n versions of all of the burgers there are available.
