Looks like we're heading to a field in Kent in 10 days, so looking at booking at the following, both of which were recommended by Stephen Harris of The Sportsman:
Folkestone Wine https://folkestonewine.com/
Angelas of Margate https://angelasofmargate.com/
Harbour Street Tapas in Whitstable is a nice spot if you are in the area and can get in. Beers in the Twelve Taps first.
