September 1 seems to be the start of restaurant closings.
Many of our favorites on that list.

I would definitely try to get a reservation at Les Galets in Les Jardins in Orient (only open fri-sunday) (doing a special meal on Saturday with live entertainment)
one of best meals in three weeks

also for lunch just south of Grand Case basketball courts, Cool Heure, a simple menu, very reasonably priced

Bacchus in Hope Estate does a fancy lunch with a great wine store attached

for great beef, L' Atlier recently reopened from vacation in Orient

Bon appetite
