Sainsburys is to close the cafe at its Eastbourne store.
Five are set to close in Sussex – Eastbourne, Crawley, Worthing, West Hove and Newhaven – with only four remaining open.
Simon Roberts, Sainsbury’s chief executive officer, said: “We are totally focused on improving what we can deliver for our customers and at the same time, working hard to make our business simpler.
“As we go through this period of transition, we have taken the difficult decision to close 200 of our cafes next month.
“We have spoken to all colleagues affected by these changes today and are absolutely committed to supporting them in any way we can during this uncertain time. Of course, we understand this is very unsettling for our colleagues, but we must keep adapting our business to make sure we are offering customers the best possible food and drink at affordable prices.”
