We just returned from a great trip to Kauai, nothing to really rave about foodwise except for a new restaurant that just opened up in Lihue called E.B.'s Eats right in the center of town on the main highway (Kuhio Highway I think). They are serving deli style sandwiches and salads, I had a great Meatloaf sandwich, my wife had a Waldorf salad that she is still raving about. We went several times, they also have this great deli case filled with all sorts of salads (tried the Wild Rice and Salmon and the Roasted Veggies) and differnt meats we had the pesto salmon one day. They say they are making all their baked goods from scratch, be sure to try the croissant bread pudding, it is addictive. I believe they also serve baked goods and coffee drinks in the morning, but we never made it there for breakfast.
We had a decent dinner at Roy's in Poipu, but would have rather saved the money and just done takeout from E.B.'s. Can't wait until our next trip. Hopefully there will be some more new places for us to try,
