Aloha...thought I'd post an update for anyone planning to visit soon.
The Beach Grill (at the golf course) is closed.
O's Bistro (in Kona) closed.
Big Island Steakhouse (the restaurant in King's shops) also closed.
Merriman's Cafe, new chef according to the waitress. Menu somewhat changed. Had one lunch there, was excellent.
Macaroni Grill at Queens Marketplace scheduled to open Nov 24. Island Gourmet food market is open. Also open, Foodland at the Shops at Mauna Lani. Between the two I prefer Foodland.
Palm Terrace breakfast buffet now $35. Closed for dinner. Waffles and pancakes no longer on the ala carte menu. Continental Buffet no longer available.
Brown's Beach House appears to be closed for lunch. I haven't verified this by calling but the website doesn't show it open for lunch and it previously was.
