Duke’s is located on property at the Kauai Marriott Beach Club, but it is independently owned and run. While there are very few gluten free notations on Duke’s menu, don’t let this deter you from dining here. It was probably the best dinner experience we had while staying on Kauai (but admittedly, we only rotated between a few restaurants). But we liked Duke’s so much we went back a second night, and it is not cheap (nothing on Kauai is!) Steaks and seafood are the specialties here. They offer plenty of steaks, which they can safely prepare gluten free. They got rave reviews from family and friends who ordered them. The ribs are also gluten free without the sauce, and various types of fish can be prepared gluten free. There is one delicious shellfish dish on the menu that actually is MARKED gluten free as it comes (no changes in preparation needed). It is a combination of shrimp, scallops, and fish in a coconut curry broth with spinach and mushrooms. Both my son and I each ordered that (on separate nights). There is also a salad bar that can be added to any entrée for an additional $4. That has plenty of GF options, but of course, you can’t have the homemade bread or muffins at the salad bar. And you can’t have the fries here, but steaks are typically served with mashed potatoes anyway, and the seafood dishes are served with rice. The one disappointment at this restaurant was that their specialty dessert is “hula pie,” which is a huge wedge of macadamia nut ice cream pie topped with fudge and whipped cream. The problem is, it has a chocolate cookie crust. Unfortunately, they were not able to give our son the ice cream and fudge (both gluten free) without the crust. (They use all the ice cream they order to make the pie – they slice big circular bins cross-wise to form the full pies.) We inquired about having them make a pie without the crust for our large group (9 of us), but that would entail us buying the full 8-piece pie at $11 per slice! Not something we were interested in doing, based on the price and the fact that, for 9 people, you really only need 3-4 pieces of pie! I wish they had some more exciting desserts for gluten free folks. They had fresh raspberry sorbet, but that’s not particularly exciting for a 14-year-old boy when everyone else can eat hula pie!
