Just spent a week on Kauai. Home base was the St. Regis Hotel in Princeville. Here are our restaurant experiences.
Tavern -- in the clubhouse of the Prince golf course. Nice room. Can get very loud. Service was excellent. Food was OK. Interesting burger with battered and deep-fried bacon slices. Expensive.
Nalu Kai Bar & Grill -- the pool bar at the St. Regis. Food was pretty good. Burgers and salads were the main deal here. Expensive for a poolside bar.
Makana Terrace at St. Regis -- This is the second restaurant at the hotel. Kauai Grill is their more expensive, fancier place. Prices at the Makana Terrace for fish dishes are $40-46. Beef dishes about the same. Wife's six-ounce filet mignon ($46) was good, not great. My lamb shank ($46) was also good. Service fell flat a couple of times when we counl not find our server.
Kalypso's -- just awful. Fish and chips, fish tacos and nachos were uniformly bad.
Mediterranean Gourmet -- Interesting place. Relatively reasonable prices. Lots of Greek dishes. Fair to good food. Service was friendly, but hard to get their attention.
Garden Cafe at Common Ground -- great lunch place. Way laid back. Food was good. I had the best piece of fish there that I had the whole week. It was Ono and was fresh, moist and good. Since you basically wait on yourself can't comment on service. Moderately priced.
Kauai Ono 560 -- Best meal we had. This place is much-discussed on this site, as well at TripAdvisor, Yelp, Urban Spoon, etc.so won't belabor it. 5 courses prepared in a food trailer and served at communal picnic tables under a big white tent. BYOB. $50 per head before gratuity.
Bar Acuda -- tapas place. Food was good, if a little expensive for what you get. Service was wonderful.
St. Regis wedding reception -- we attended a wedding reception held on the Bay Terrace at the St. Regis. Huge buffet with 8-10 entrees, uncountable salads and desserts. Food was OK. Beverage and bussing services were good. Not bad for a large buffet.
Pau Hana Bar & Grill -- went because of great reviews of the fish and chips. They were good. Certainly better than Kalypso's! It's sort of a hole in the wall in a shopping center in Kaapa. Worth getting a meal there. Moderately priced.
Kauai is a beautiful island, but the food was, overall, disappointing. Someone said Hawaii is not famous for its food. Good thing.
