Within walking distance, you have Big Fish. Daniel's by the Sea/Busby's is also right there, but nothing special IMO (although Daniel's has a following).
On the other side of Oyster Pond, Capt. Oliver's, Le Planteur, La Fregate, and Quai Ouest are all good.
More casual/basic food options are the Dinghy Dock and Mama's Pizza.
I would not bother with the restaurant
